Collison was a beast when he was in NO before in place of CP, and Hansbrough could be a borderline 20/10 guy with consistent starter minutes. Depending on what picks were included, I think thats a deal that could look very smart in the future.
Hansbrough is a good effort guy. A PF most teams would like off their bench.
Collison is a solid starting PG that can hang big stats playing on a bad team.
Both are nice pieces, but not centerpiece of a trade that makes Rondo or Paul move.
I think hansbrough could easily develop into a carlos boozer level player...bordering on a 20-10 every year with good energy
If you lose CP, and gain a young player with 20-10 potential, a solid starting PG, and 2 1st round picks while dropping a bad contract (ariza) from your books, I dont think it's that bad.
Obviously CP is still far and away the best single item, but thats a lot of quantity to get back. With curry and Gordan off the table, and no interest in rondo, that might be an attractive deal.
