I'm not sure if Perk will EVER be replaced. He brought a lot more than just tough interior defense, garbage buckets, and shot-blocking.
He brought UBUNTU. He took a HUGE portion of that with him when he went to OKC.
Great thing is that Pietrus seems to have replaced a lot of that UBUNTU.
Stiem? I really like the man. He is getting there for us..gives great effort on defense...timely shot-blocking...he is rather tough inside.
If Stiem can give us close to what Perk gave us when he was here, that is reason alone to sign him for a few years, as KG wanted.
As some have noted in the thread, KG makes just about any big we have look good.
Plus, if Stiem can throw in one of THESE next time we play MIA, that would help his cause, too:
