I dont know if his knee is still bothering him or he is just plain not having any fun.The lions only have one victory and I understand all the players are beat-up by this time of the year ,but when you look on the sidelines at least most of the players are still enjoying playing the game.CJ looks like he's going through the motions and does'nt seem to have a rapport with Staff.In my opinion I think he's just not happy in Detroit.
