McCoy rushed just six times Sunday, for nine yards. Five of those yards came on one carry.
He also didn't start the game against the Partiots, making it his first missed start in a game in which he participated since 2010. The explanation afterward was vague, but not controversial.
It didn't work, and it showed in the time of possession difference. Oh, and the final score: a 24-10 Patriots win.
Perhaps more concerning, though, is the season-long performance of McCoy, who has battled injuries and rushed for 479 yards and two touchdowns in 12 games. He's carried the ball about half as many times as he did last season, in which he averaged 4.0 yards per carry and gained 1,138 yards on 287 totes. He also hasn't had much help when running the ball behind a variety of backups (Nathan Peterman, Derek Anderson, Matt Barkley) in place of Allen, who has missed time due to injury this season.
McDermott had also mentioned in the lead-up to Week 16's game that he'd like to get Ford more touches after the rookie gained 46 yards on 14 carries, making this a little less startling.
At 30 years old and with just one year left on his contract, though, this might the beginning of Buffalo looking beyond McCoy.
