This thread makes me sad. 
Why? I think when it's all said and done, both OKC and BOS will make out in this trade...I really do.
Jeff (and Nenad, too) seemed to making strides there towards the end of the MIA series.
With a full training camp, both will be even better acclimated to what Boston does.
Perk, while clearly not quite himself this season, will be fully healed next season. He and Serge will form a formidable frontline to matchup with MEM and LA for next few years, plus they have Nick Collison and Nazr backing them up.
Most of us miss Perk, but he'll be fine.
