Mark Ingram was a success story last year for Fantasy owners. So were Ben Roethlisberger, Jeremy Hill, Kelvin Benjamin and Travis Kelce.

What do they all have in common? They were some of the sleepers we listed during our three-part series last season.

And now we're back to do it again. Our first sleeper's column is prior to free agency and the NFL Draft, but these are 12 players who you might want to put on your radar this summer.

We'll revisit this column again prior to training camp and then at the end of August. The goal is to find as many late-round options as possible to help you win your league.

Eli Manning, QB, Giants

You might be surprised to know that Eli Manning was No. 11 in Fantasy points in 2014 in standard leagues and just one point behind Matt Ryan for No. 10. Despite his reputation for being a less-than-stellar Fantasy option, he's actually been a Top 12 quarterback five times in the past seven years (he was No. 21 and 15 the past two seasons, respectively). Last year, Manning had nine games with at least 20 Fantasy points. He benefitted immensely with the addition of Odell Beckham, and the hope is Victor Cruz (knee) will make a full recovery in time for training camp. With Beckham, Cruz, Rueben Randle and Larry Donnell, Manning should have the best receiving corps of his career. He attempted a career-high 601 passes last season in new offensive coordinator Ben McAdoo's system and completed a career-best 63.1 percent. Another season of 4,400-plus yards and 30-plus touchdowns is definitely possible, and Manning is a great quarterback to wait for on Draft Day with a late-round pick.

LeGarrette Blount, RB, Patriots

The depth chart for New England's backfield is sure to change between now and August, but the Patriots could conceivably go into the season with LeGarrette Blount, Jonas Gray, James White and Brandon Bolden as their top guys. Stevan Ridley and Shane Vereen are free agents, but Blount might prove to be their best running-downs rusher. In five games with the Patriots in 2014, Blount averaged 4.7 yards per carry. He averaged 5.0 yards per carry in 2013, and he ha s been successful when given a heavy workload. In 25 games with the Patriots, including the playoffs, Blount has 10 games with at least 12 carries. In those outings he has double digits in Fantasy points six times, including 14 total touchdowns. He's obviously not going to help in PPR leagues with 12 combined catches the past two seasons, and he's still a Bill Belichick running back, meaning plenty of uncertainty on a weekly basis. But if he enters the season as the potential starter then he's well worth a mid-round pick. Belichick obviously trusts him (he's lost three fumbles in his past 319 carries), and when he touches the ball enough he has a good chance to succeed in a big way.

Khiry Robinson, RB, Saints

Khiry Robinson's Fantasy value is almost directly tied to what happens with Ingram, who is a free agent. Ingram had a career season in 2014 with 226 carries for 964 yards and nine touchdowns and 29 catches for 145 yards. He is expected to leave the Saints in search of a big payday, and Robinson should be the next man up. Pierre Thomas will likely remain a factor, but ESPN reported in January that the Saints were ready to increase Robinson's role last year before he suffered a fractured arm in Week 7 and missed seven games. He averaged 4.8 yards per carry last season and 4.5 yards per carry over two seasons in New Orleans. When Ingram missed three games with a broken hand last year, Robinson had 18 carries for 69 yards against Minnesota, eight carries for 87 yards and two catches for 18 yards at Dallas and 21 carries for 89 yards and a touchdown against Tampa Bay. He is a tough runner at 6-feet, 220 pounds, and New Orleans can definitely lean on him as Ingram's replacement if that's what unfolds this offseason. If Robinson is the starter for the Saints in 2015 he would definitely be worth a mid-round pick in all standard formats.

Charles Sims, RB, Buccaneers

We heard a lot of talk last season about the Tampa Bay coaching staff being high on Charles Sims, who was selected in the third round of the NFL Draft last year from West Virginia. The reports are already the same this offseason, according to ESPN, but now Sims has to produce. An ankle injury kept him out for the first eight games last season, but he finished with just 66 carries for 185 yards and a touchdown and 19 catches for 190 yards. He had one game with a full workload, which was Week 17 against New Orleans, and he played well with 18 carries for 69 yards and a touchdown and one catch for 6 yards. Doug Martin should remain the starter this season, but Sims will definitely get his share of touches. His value is likely higher in PPR leagues, and he had four games of the eight he appeared in with at least three catches. But if Martin continues to struggle (he averaged just 3.7 yards per carry last season) then Sims' role would definitely increase. He's worth a late-round pick in all formats and could be a steal on Draft Day.

Lorenzo Taliaferro, RB, Ravens

Lorenzo Taliaferro might not be the ideal fit for new offensive coordinator Marc Trestman's offense, but Trestman has said he plans to build on what Gary Kubiak did last season. If that's true, and Trestman is known more for his passing prowess then running success, then Taliaferro could be a nice replacement option if Justin Forsett leaves the Ravens as a free agent. But regardless of what Trestman does, and even if Forsett returns or another running back is brought in, the Ravens will carve out some sort of role for Taliaferro this season. He was drafted last year in the fourth round from Coastal Carolina, and he had some positive production in limited work with 68 carries for 292 yards and four touchdowns and eight catches for 114 yards before going on injured reserve in Week 15 with a foot injury. He only has 35 catches in two years in college and last year in the NFL, but he could be a beast between the tackles at 6-feet, 226 pounds. We'll find out what the Ravens plan to do with Forsett or another potential replacement, but I plan to gamble on Taliaferro with a late-round pick in all standard leagues.

Theo Riddick, RB, Lions

It would make sense for the Lions to move on from Reggie Bush this offseason after he struggled with injuries and poor play in 2014. He averaged a five-year low 3.9 yards per carry, and he was limited to just 11 games. When Bush was out, Theo Riddick showed he could be a quality playmaker out of the backfield as a receiver, which would be a perfect complement to Joique Bell. In Week 6 against Minnesota, with Bush out, Riddick had five catches for 75 yards and a touchdown. And again in Week 8 at Atlanta without Bush, Riddick had eight catches for 74 yards and a touchdown. He had four games with five catches or more in limited playing time (he finished with 34 catches for 316 yards and four touchdowns on the season), but he could be a solid PPR option if he was No. 2 on the depth chart behind Bell. His rushing numbers were non-existent (20 carries for 51 yards), but he could be a similar Fantasy option to Vereen or Darren Sproles. He could easily reach 50 receptions if Bush is gone, and 60-plus catches in this offense is a definite possibility.

Jarvis Landry, WR, Dolphins

Last year's rookie receiver class was amazing and led by Beckham, Benjamin and Mike Evans. We also had strong performances from Sammy Watkins, Jordan Matthews and Martavis Bryant. But quietly we saw Jarvis Landry have a nice season for the Dolphins. He was second among rookie receivers in receptions with 84 (Beckham had 91) and was one of 17 receivers with 80-plus catches. He had five games with seven-plus catches, and he finished with 758 yards and five touchdowns. We need to see more from Landry to help Fantasy owners in standard leagues, and hopefully he becomes more of a focal point this season than Mike Wallace. They were close in targets (Wallace had 114, Landry had 112), but Wallace scored 10 touchdowns with 67 catches for 872 yards. Landry should be considered a No. 3 receiver on Draft Day in all leagues, but he has No. 2 potential in PPR formats. He could easily eclipse 90-plus catches based on what we saw last season, and if he can approach 1,000 yards with 6-8 touchdowns we could be talking about one of the best value picks of the draft.

Allen Robinson, WR, Jaguars

The Jaguars receiving corps will look a little different this season with Cecil Shorts gone as a free agent. We'll find out if Justin Blackmon (suspension) is able to return and if Jacksonville adds more talent to the position, but the Jaguars will likely go with Allen Robinson, Allen Hurns and Marqise Lee as the top three targets for Blake Bortles. We hope all these rookies from 2014 continue to grow together, and Robinson showed plenty of promise last season before a fractured foot ended his year in Week 10. He finished with 48 catches for 548 yards and two touchdowns on 81 targets, and he's expected to be ready for the start of offseason workouts. Bortles should continue to improve in his second year, and he should continue to rely on Robinson, who led the team in targets before getting hurt. Most of his production came from Week 2 to Week 10 when he averaged 5.2 catches for 61 yards and 0.22 touchdowns. If you project that over 16 games, Robinson would have averaged 83 catches for 976 yards and four touchdowns. That makes him a solid No. 3 receiver coming into the year, but there's a chance for him to emerge as a No. 2 option if he progresses as we expect.

Cody Latimer, WR, Broncos

Cody Latimer's Fantasy value this season is dependent on two things: Peyton Manning's future and Wes Welker's free agent status. If Manning returns as expected that should keep the Broncos' passing game at a high level, even with Manning struggling down the stretch last season. And if Welker doesn't return to the Broncos as expected then that opens the door for Latimer to get more playing time. He barely saw the field as a rookie in 2014 with two catches for 23 yards on four targets. But if Latimer can emerge as the No. 3 receiver for the Broncos behind Demaryius Thomas and Emmanuel Sanders then he could have a quality sophomore campaign. His stock would really sore if Thomas left as a free agent, as well as tight end Julius Thomas. Latimer has plenty of upside based on how he played during the preseason last year, but the Broncos didn't need him in 2014. That should change this year, and he's a high-upside player to gamble on in all leagues with a late-round pick.

Charles Johnson, WR, Vikings

Minnesota offensive coordinator Norv Turner told ESPN at the NFL Combine that Charles Johnson is "far and away our best receiver." He showed flashes of his potential in 2014, but there's plenty of room for improvement. And we think he'll thrive this season as he enters his third year in the NFL. He finished last season with 31 catches for 475 yards and two touchdowns, but he really didn't get an extended look until Week 11. He closed the season with 25 catches for 415 yards and two touchdowns in the final seven games, and if you project that over 16 games he would have finished with 57 catches for 949 yards and five touchdowns. Second-year quarterback Teddy Bridgewater will continue to rely on Johnson, who was easily better than Fantasy bust Cordarrelle Patterson. Johnson had four games with at least seven targets last year, and he scored at least seven Fantasy points in a standard league in each one. I plan to draft Johnson with a mid-round pick in all leagues as a No. 3 Fantasy receiver with No. 2 potential.

Duron Carter, WR, Colts

The Colts appear to have a need at receiver with Reggie Wayne mulling retirement and Hakeem Nicks not expected to return as a free agent. That leaves an established star in T.Y. Hilton, a breakout candidate in Donte Moncrief and Duron Carter with a chance to be the No. 3 guy. He spent the past two seasons in the CFL playing for the Montreal Alouettes, and he caught 124 passes for 1,939 yards and 12 touchdowns. We're not sure how that will translate to the NFL, but he definitely has some skill. He went to the CFL after dealing with disciplinary and academic issues at Ohio State and Alabama, and he was undrafted in the NFL, but he's the son of Hall of Fame receiver Cris Carter. Hopefully there are some similar traits on the field for father and son, and Duron Carter should benefit playing with an elite quarterback in Andrew Luck. We'll see how Carter fits in with his new team this offseason, but if he clicks and can earn significant playing time then he'll definitely be worth a late-round pick in all leagues.

Austin Seferian-Jenkins, TE, Buccaneers

Tight end is an easy position to define this season on Draft Day. You're either going to take one early in Rob Gronkowski or Jimmy Graham, gamble on a second-tier type like Kelce, Greg Olsen or Martellus Bennett with a mid-round pick or just wait out the position to see what falls to you in the later rounds. That's where Austin Seferian-Jenkins comes in. He had a minimal impact last season as a rookie with 21 catches for 221 yards and two touchdowns on 37 targets, and he was limited by ankle and back injuries, the latter of which forced him to injured reserve at the end of the season. New offensive coordinator Dirk Koetter, who worked with Tony Gonzalez at the end of his career with the Falcons, expects to use Seferian-Jenkins quite a bit as a complement to Evans and Vincent Jackson. The Buccaneers will most likely have rookie Jameis Winston or Mike Glennon at quarterback, so there could be some growing pains there, but Seferian-Jenkins is a late-round tight end with upside. If he falters, you can cut him and start streaming tight ends for the rest of the season.
