I doubt the wolves do that trade, however, if they would, I would jump at it. The C's could get a real building block with the #4 pick, who could really help this team to build their new core with Rondo. Then the C's can either move KG to center, or go after a guy like Haywood to replace Perk.
While Perk is great, I don't think there is anyway he is worth that high a pick, and he is going to be overpaid after next season IMO. I also think he may be a bit overrated defensively at times, just because he does so well against Howard and Shaq. Yes, he is probably the best in the league guarding those guys, however, against the quicker, more skilled centers, he is very average. If they can get a top level talent, I think that would be more valuable than Perk's ability to minimize Dwight Howard (besides, if Perk is the best Howard stopper in the league, Davis and Sheed might both be in the top 5 as well).
