ESPN's John Clayton reported McCargo failed his physical with the Indianapolis Colts one day after the Bills thought they had ridded themselves of the underachieving defensive tackle.
The Bills traded up specifically to draft McCargo 26th overall in 2006. He never started a game and was inactive for the season opener. He had played in Buffalo's past four games, but the Colts found a damaged disk and voided the trade, which was for a fourth-round pick.
"It is our understanding that John did not pass the physical administered by the Colts, and so he remains with the Buffalo Bills," said Bills spokesman Scott Berchtold.
McCargo's departure mostly was met with shrugs in the Bills' locker room. Guys who assumed they were McCargo's former teammates this afternoon knew he wasn't fitting in with the team dynamic.
Bills defensive line coach Bill Kollar had this to say in Wednesday's edition of the Buffalo News.
"It's like we've said from Day 1, you've got to really want to play," Kollar told Buffalo News reporter Allen Wilson. "It's real easy to go and talk about it. But what you have to do is work and get better on the practice field and take it into the game.
"He's got the ability. But deep inside yourself you've got to want to end up getting it done. You've got to end up doing it on the field."
The Bills clearly had given up on trying to mold McCargo into a more serviceable player.
To welcome McCargo back now would be difficult for the Bills and dangerous for team chemistry moving forward. Teams don't need grousing players in their locker room.
