interesting. not sure how i feel about it, but i see your rationale. in your mind, if we keep zbo we probably lose OJ, Arthur and Speights. But if we deal Zbo we can sign all of the FA's. its basically a big gamble on Darrel Arthur. If he was healthy it would really make sense. you just slide him into the role zbo is filling now.
If we would ever make deal with Zbo, not that I like that much, we should give reasonable contracts for the rest of the players (I don't know if the FO know how to do that) and would be like this...
TA/OJ/1st round pick
trade Zbo for J Smith like someone mention before... this guy has a chance to the give to the frontcourt the same type of effective TA give to our backcourt... I think we would be able to keep OJ and Speights for sure and DA will probably be cheap so him too, but Arenas depends of how he play in the playoff and if he want to go to another market.
