That seems to be an excellent question. Yes, we may be able to get decent talent in a trade for Stat and Nash, but who the hell knows what will be an available alternative as a max player? Most of the star players that will be available in the near future will want to join successful teams, teams with championship potential. If we do nuke the current group, what great player would want to come here anyway?
Is Amare going to be a Tim Duncan max player? Unlikely, but could he be a Paul Pierce max player? I think so. It's amazing, a couple years back Pierce was considered a me first chucker who needed to be dumped from the Celtics so they could rebuild. Add two great players around him, and now he's a team leader and the heart and soul of the team.
While Amare has his shortcomings, I'd rather take a chance on the bird in the hand. The question the FO should be asking itself isn't "is Amare the perfect player, without any shortcomings?" rather "can we build a championship team with Stat as a max player?" The answer to the first question is no, while the 2nd is possibly, if you can build the right supporting cast around him.
