No thanks.
Kaman isn't that good. Every bit as slow as JO. Maybe a bit better on offense, but not that much. I'm not even sure he's any more reliable health wise either. I just don't see Kaman having a significant impact on our fortunes for this season. And no way would I want to keep him next year. He will be overpaid. Perk's contract is a better bargain than what Kaman will likely recieve.
Considering the only way to make a trade work, would be to include other players (besides JO), I just don't see any value on our side in any trade for Kaman. A one year rental for a marginal player is not worth giving up any of our young players.
Man, maybe you have seen Kaman play, but I disagree with the majority of your thoughts, especially the ones in bold.
Here's a recent video of him playing for Germany. He was often matched up vs. Asik, who many here love, and Semih, who everyone here knows. I thought this was an appropriate video since he was starting and getting significant playing time, is a recent game (didn't want to post an LAC game from 5 years ago), and was going up against NBA caliber centers.
If you watch his game, especially his post game and footwork in the post, and still feel the same, then to each his own.
