The Bills signed Reggie Bush this offseason and he's expected to play a role behind LeSean McCoy as a reserve running back. Following Karlos Williams being released, Bush could be the No. 2 ahead of Jonathan Williams and Mike Gillislee. Last year, Bush was a reserve with the 49ers, but he suffered a torn meniscus and was limited to five games, finishing with only had eight carries for 28 yards and four catches for 19 yards. At 31, it's hard to see Bush playing a prominent role this season, especially coming off a knee injury, but he could still be useful as a third-down back. If you're looking for a handcuff option for McCoy, Bush could be worth a late-round flier.
