The Bills signed Reggie Bush earlier in the week, and the veteran will likely compete with Williams and others for playing time behind LeSean McCoy.
Despite a recent DWI arrest, Williams will have a fair shot to earn that key No 2 role, a path made easier when Karlos Williams got himself suspended for four games. While it theoretically was made more difficult with Bush coming aboard, his signing may have as much to do with the team's lousy return talent as anything else. As for the first quarter of the season, Williams will compete with Bush, Mike Gillislee, James Wilder, and Dan Herron for RB slotting.
