If you drafted Bears quarterback Justin Fields expecting that he'd build upon his 2022 season with a revamped offensive line and the addition of D.J. Moore, chances are your season hasn't gotten off to the greatest start. Now you might be in the market for a new Fantasy football quarterback. Working the trade market might help solve that issue but the cost for a QB1 can be prohibitive. Working the Fantasy football waiver wire to find a quarterback with long-term potential or working the matchups and streaming a QB might be the more cost-effective option.

Texans quarterback C.J. Stroud has been the most impressive rookie quarterback in the NFL through three weeks and the former Ohio State star is still available in 66% of CBS Sports Fantasy football leagues. So how much of your FAAB should you be spending on a QB like Stroud, and who else should you be targeting on the Week 4 Fantasy football waiver wire? Before making any Week 4 Fantasy football waiver wire claims, be sure to see what SportsLine Fantasy football analyst Jacob Gibbs has to say.

Gibbs uses a data-driven approach that has helped him consistently provide accurate rankings at every position. He has proven to be one of the nation's most accurate Fantasy rankers in recent years -- posting the eighth-most accurate results over the past three seasons, according to Fantasy Pros.

Now, he's revealed his top waiver wire pick from among the widely available Fantasy football free agents entering Week 4. You can see his top Fantasy NFL waiver wire picks and full analysis over at SportsLine

Top Fantasy football waiver wire picks for Week 4

One player Gibbs is advising Fantasy players to target on the Week 4 waiver wire: Dolphins running back De'Von Achane. The Texas A&M product doesn't have prototypical size at 5-foot-9 and 185 pounds but he does run the 40-yard dash in 4.32 seconds and he put that speed on display in Week 3 against the Broncos.

Achane missed Week 1 with a shoulder injury and only played six snaps in Week 2 but he made the most of his 30 snaps in Week 3, carrying the ball 18 times for 203 yards and two touchdowns while catching four passes for 30 yards and two scores. His backfield mate Raheem Mostert also scored four times last week and while that won't be normal production, this Miami offense does make it look like there will be enough work to go around for both backs and Achane is still available in 43% of leagues.

Gibbs is also strongly recommending Texans wide receiver Nathaniel Dell. Better known as "Tank," he finished his career at Houston with back-to-back 1,300-yard seasons and the Texans spent a third-round pick in the 2023 NFL Draft to keep him in H-Town. Dell has quickly built a rapport with Texans rookie quarterback C.J. Stroud and his involvement in the offense has continued to grow over the first three weeks.

He's been targeted 21 times over the first three weeks and has caught 15 passes for 251 yards and a couple of touchdowns. He's coming off a 145-yard performance in Week 3 and has caught a touchdown while producing at least 20 points in PPR leagues the last two weeks and is still available in 44% of CBS Sports Fantasy football leagues. See who else to target on the Fantasy football waiver wire at SportsLine
