I should have also asked, would you have left if you were Tim the previous time you could have? Right now, sure, you probably wouldn't as it's a little late to start over on a new team.
I think Tim could have opted out a few years ago though couldn't he have? I would have seriously considered leaving around that time if I was him, basically about the time Pop started Bonner and decided to include him into the rotation, permanently.
At the very least I am surprised that Tim hasn't asked the team to get rid of Bonner. I don't see how he could like busting his ass all season, only to see Bonner get scared in the playoffs and curl up into the fetal position when there is a pressure game or situation. I just couldn't work with someone like that if my main goal was to win a Championship. Bonner is a great guy at all, but he's just not a championship player or someone you can have in the rotation if you are looking to win, and it seems like Tim is OK with that as it doesn't seem as if he has done or said anything about it. Personally, I would be more OK playing with Dejuan over Bonner as he gives effort and doesn't get scared out there, sure he may be limited, but at least he will give it full effort out there and not pack it in.
