Here comes Reggie: Bills sign RB Bush

With all the uncertainty at the running back position after starter LeSean McCoy, the Buffalo Bills are about to bring in another high profile name to compete for playing time.

According to multiple reports, the Bills have signed free agent running back Reggie Bush to join the team's backfield. This would be the fifth stop in Bush's career, after having played for the New Orleans Saints, Miami Dolphins, Detroit Lions, and San Francisco 49ers.

The Bills confirmed that Bush was indeed visiting with the team on Monday.

Bush, 31, had his season cut short after he suffered a torn ACL in 2015 as a member of the 49ers. He's been a free agent since March. The Bills likely made the move due to the announced four-game Karlos Williams suspension for violating the league's substance abuse policy.

Joe B's Take

With the expected addition of Bush to the roster, he can impact the roster in a few different ways. While they should still give an opportunity to someone like Mike Gillislee, who had the best crack at the complementary job without Bush on the roster, it creates even more legitimate competition for the position.

Bush can help out on third downs as a pass catching back, which would allow McCoy to get some rest and not carry the entire workload. Pass catching is a strength of Bush's game that Gillislee did not show in his time on the field with the Bills in 2015.

The former USC star and second-overall pick could also factor into the special teams game as well -- most notably, as a kick or punt returner. Neither of those jobs are settled for the Bills, and with experience doing both, Bush could become the odds on favorite to win those jobs if the team would like to subject him to it.

The move also means James Wilder, Jr., Jonathan Williams, and Boom Herron will have to convince the coaching staff to keep a fourth running back on the roster through the first four weeks, and the only way to do so will be through special teams coverage units. If they keep a fourth for that reason, Wilder, Jr., has the most upside in that part of the game.

I don't think it's a given that Bush automatically takes over the number-two job with Karlos Williams being unavailable for the first month of the season, but Gillislee will need to do a great deal to convince the coaching staff that he's the most multi-faceted threat to complement McCoy at the start of the season.
