TP KGsKnee! I wrote this and was about to post it when I saw yours. Pretty much what I was thinking:
I personally think he is done playing basketball for a living.
From a selfish Cs fan standpoint, I hope he shakes it off and comes back and plays to the level he was playing at before the injury. From a realistic standpoint based on past performance (last year) psychologically and physically I don't think it's going to happen or should happen.
I don't know Quis' personal $$$ situation, but if he is comfortable financially, he should walk away while he can still walk. I know that is an intensely personal decision for him and his family to deal with. Maybe he's willing to risk permanent, crippling damage in order to have his family be financially secure, if they already aren't. That's up to him.
Given his style of play, which is predicated on driving to the hoop and scoring in the paint, and given his proclivity for this type of injury, I wish him and his family much luck.
Whatever he decides, let's get him a ring in June!!
