i agree with this to a certain extent, but i have to play devil's advocate here. if he is on the team and his heart and head are not in the game, if he is not giving forth the effort and commitment demanded to play in the nfl, then he is doing a huge disservice to his teammates and coaches. if this man has no more love for the game and no will to carry on, it is better to leave now then become a distraction/locker room cancer.
butler seemed to be a lot more passionate about his life off the field than on, and i have no ill will towards him. in fact, i have a lot of respect for him. to be an nfl player i think you need to be all in, it's definitely not a career choice you can just half-@$$.
