What began as good-natured ribbing between teammates seems to have taken a turn for the sour over accusations of cheating.
Last week, after weeks of teasing from his Philadelphia Eagles teammate, running back LeSean McCoy, quarterback Michael Vick accepted a challenge to race.
Vick, 32, had reportedly had enough of McCoy, 24, teasing him and calling him "old man," and got permission from coach Chip Kelly to race during practice last week.
The "old man" crushed the competition, beating his younger teammate by about five yards in the 40-yard race.
But now, McCoy is accusing Vick of cheating, saying the quarterback left before the gun, and he says he has proof.
Vick hasn't replied to the "accusations," nor has the video proof surfaced. Somehow, it's safe to bet fans won't care either way if the team plays well.
