Aside from his contract, though, Boozer is not attractive for the same reasons Pau isn't attractive: old and declining, and -- here's where the contract DOES come into play -- not likely to be moveable in 2 years when he's expiring, if you assume he continues to get older and keep declining. He also doesn't play a lick of defense; he's probably worse than Bargnani.
Toronto stands to gain nothing from this deal outside of a possible 3-5 additional wins this year (at the expense of developing the younger players), which makes it hard to accept the idea that Chicago would actually be looking at MORE return... IMO, to be remotely possible, Chicago would have to keep Nate Robinson and give Toronto Teague instead. And BC could throw in Anderson along with Lucas, who Chicago apparently wants back.
This is a lot like the Gay deal -- Chicago is looking to dump Boozer, not get anything back for him. They know he's tough to move, so they're basically saying "take our crap, we'll take yours".
