On Saturday the Bills released the running back and Williams cleared waivers Monday, becoming a free agent.
"So in light of that we thought, why hold on to him, why don't we give him a chance to maybe find another job out there in the league? We weren't going to hold on to him to the end knowing he wasn't going to make the team."
Williams infamously started camp on Buffalo's active/non-football injury list after showing up 20 pounds overweight. The second-year power back admitted in June that he tacked on the extra heft while tending to -- and eating with -- his wife during her pregnancy. A noble gesture, but not what the Bills were expecting.
Coach Rex Ryan, loyal to a fault with his players, assured reporters earlier this month that the back's roster spot was safe, saying: "We're not going to give up on Karlos Williams. I can tell you that."
While surprising, it's an understandable move by the Bills. The Williams saga was an unnecessary drama for a team that has already been blitzed by the injury bug. Buffalo needs healthy players more than it needs an overweight, suspension-addled back who doesn't appear plugged in to the task at hand.
