Ke'Shawn Vaughn might not be a household name, but he could emerge as the top pass-catching option out of the backfield in Tampa Bay.The 49ers normally prefer a committee approach, but Raheem Mostert deserves an increase in touches. Dede Westbrook seems like a great fit for the offense Jay Gruden is bringing to Jacksonville. Even with CeeDee Lamb in the mix, Michael Gallup should still be in for a good season. D.K. Metcalf got better and better as his rookie season progressed, so he should be in for a big year in 2020. If Baker Mayfield struggles this season, Case Keenum could get an opportunity to start some games. With Jay Gruden calling the shots in Jacksonville, Gardner Minshew could take a big leap. If Jones can cut down on his turnovers, he could end up being a fantasy QB1 next season. If Derrius Guice can stay healthy, he should be the lead back in Washington. Kerryon Johnson is too good not to get touches, but the Lions clearly have big plans for D'Andre Swift. Ronald Jones was the lead back for Tampa Bay last year, but third-round pick Ke'Shawn Vaughn is ready to push him for playing time. Raheem Mostert took over as the top back for the 49ers last year, and he should hold that spot in 2020.
