Via the MLE, LLE, or vet min (let's say McDyess or Rasheed) - how about
this trade to add some depth at the center spot.
It would save Memphis a million or so, more if Scal or Tony took a buyout (or they don't pickup Pruitt's contract.) And Darko could be useful for extra size off the bench. Since he'd be the fourth or fifth big man, and his roll would be just to bang with a guy like Howard or Shaq, or put a hand up on Big Z or Yao, I think he'd fill that roll okay. They could resign Powe as the depth at PF - and that would give more minutes early to see how good he can be. A 13 PER isn't great, but its okay from your 10th or 11th guy off the bench. At 23 and with a most comparable at age to Jermaine O'Neal - I think he still could be a late bloomer.
Anyways this is just a tactical move to fill out the roster more efficiently, not a big strategic change.
