The ACC enters 2012 with arguably the deepest crop of quality quarterbacks in league history. Here is how the 10 returning starters rank:

1. Logan Thomas, Tech" data-canon="Virginia Cavaliers" data-type="SPORTS_OBJECT_TEAM" id="shortcode0"> -- An argument can be made for each of the first four quarterbacks on this list, but in Virginia Tech’s last nine games, Thomas threw 15 touchdowns and rushed for 10 more. He was the league’s best quarterback the second half of the season.

2. Tajh Boyd, Clemson -- Boyd led Clemson to its first ACC title in 20 years in his first season working with offensive coordinator Chad Morris. He threw seven interceptions in Clemson’s four losses compared to just five interceptions in the team’s 10 wins.

3. EJ Manuel, Florida State -- It doesn’t feel like we’ve seen the best of Manuel. He completed 65 percent of his passes last year while dealing with his own injuries as well as injuries throughout the offense. He’ll have to deliver in a major way for Florida State to meet expectations.

4. Mike Glennon, NC State -- His 31 touchdown passes in 2011 tied for second in school history, only behind Philip Rivers. Glennon spread the ball around last year with six different players catching at least 25 passes.

5. Tevin Washington, Georgia Tech -- It’s tough to figure out where Washington fits in a list like this given the offense he runs. He’s effective running Paul Johnson’s system as Georgia Tech ranked No. 3 nationally with 5.7 yards per carry in 2011.

6. Bryn Renner, North Carolina -- Renner led the ACC in passing efficiency (159.4), but he also led the league in interceptions (13). He’ll lead new coach Larry Fedora’s up-tempo attack.

7. Tanner Price, Wake Forest -- Price enters this season having thrown 173 consecutive passes without an interception, the seventh longest in ACC history. He’ll miss Chris Givens, the league leader in receiving yards last year.

8. Michael Rocco, Virginia -- Rocco is the starter, but he will get some competition from Alabama transfer Phillip Sims in preseason camp. Rocco led Virginia to its first bowl game since 2007.

9. Sean Renfree, Duke -- Renfree enters his final year at Duke as the most accurate passer in Duke history (63.4 percent). He has to take better care of the ball as he threw at least one interception in the last seven games of 2011.

10. Chase Rettig, Boston College -- Rettig will be working in his third offensive system in three years at Boston College. New offensive coordinator Doug Martin will try to get the most out of Rettig, who completed just 53.6 percent of his passes last year.
