Ainge didn't wanna pay him for 4 years. If he could, he would've paid for two. The first two, not the latter two.
I love Po-Z, but at this point, I would want him back if he were part of a bigger deal.
I don't doubt he could perform better than last season, and his locker room effect is immeasurable. But for 'Sheed's contract, I think we could find a better long term solution.
