The Facts: Williams has had a rough offseason, but the Bills still see him as part of their future. "We're not going to give up on Karlos Williams. I can tell you that," HC Rex Ryan said, via Chris Brown of the team's website.

Diehards Line: Williams showed up to OTAs overweight and isn’t practicing at camp while he’s trying to get himself in better shape. Doing so won’t get him on the field for the first four weeks of the season thanks to his suspension for violating the league’s substance-abuse policy, something that contributed to the team’s decision to sign Reggie Bush this week. The Bills also have Mike Gillislee and rookie Jonathan Williams on the roster behind LeSean McCoy, but Ryan said Tuesday that the second-year back remains in the team’s plans. As PFT suggests, it’s not hard to figure out why the Bills want Williams around. He ran 93 times for 517 yards and seven touchdowns last season and added two more scores on receptions for the kind of production any team would like from a backup running back. That could change with continued non-football foul-ups, but it seems Williams will get the chance to resume his rookie role once he gets his other issues under control.
