Are you looking to replace Bargnani's production (which you continue to argue is non-existent) or are you looking to improve the team? Boozer in brings short-term gain only, contract notwithstanding, which I argue will be a negative longer term regardless of cap impact.
I think you're just in a hurry to get rid of Bargs. That's a bad objective, IMO, because my argument is that, while he's eating $10M in salary for the rest of the year, he's NOT having any other significant negative impact on the team, the development of younger players, etc. You can continue to argue that Boozer won't have any other negative impact, either, and that's where, yes, we will agree to disagree.
Again, to be clear on MY perpsective on this for the last time: Move Bargnani. But move him for something that doesn't have massive potential to make this team worse over the long haul, not better.
