Amare's contract will be an albatross if he can't play this season; No thanks, pass for me.
Well, the benefit is that Amare's deal only has 1 year left after this season, compared to the 2 years left for Wallace.
What this deal does is maximize cap space for the C's in the summer of 2015. It also does give them an interesting chance to keep a winning (or at least entertaining) team for the near term, if Staudemire can somehow get healthy.
While he will never be the player he used to be, the C's would be able to put him at center, which could help him get close to where he was before Melo and Chandler came to NY. He is one of the best pick and roll big men in the league, and would really help Rondo, and could fit in well with a fun, up tempo team, as the C's continue trying to collect assets and develop young guys.
And next season, he will be tradable as an expiring contract...although with a contract his size, it won't be easy to find a match.
This deal is by no means a home run. But it is the kind of realistic deal that works for both teams on some level, that could actually happen.
