I still see a way for this pickito eventually work out...but it requires a leap of faith.
The model: Kevin McHale. Back before he was a sad *** excuse for a GM. 6'11". Pasty. Had a body like a taller Tayshaun Prince, minus the athleticism, and then you threw on Lurch's/Frankenstein's head. Poor athlete, ran funny. But in his prime was very VERY effective as a PF because he knew every single post move, and their counters. Almsot impossible to stop because you couldn't take it all away. You take away one shoulder, he went the other way just as well, you bite one fake, it was over. You don't bite, it was over. And he was never a very good rebounder. Just such a prolific and skilled scorer that that was a nitpick rather than a devastating problem. Thing is that while he was not a good rebounder he WAS a tremendous defensive player. Made All Defensive teams. And used his long long arms and timing to block shots, disrupt, and intimidate anything inside. That's where hope breaks down a bit. Even if Hawes could be that kind of post player, without that second dimension, McHale's legacy would have been shaky (and the Celtics titles during that era fewer). What ELSE is Spenser Hawes going to do for you is the question. When the play is not called for you, when you are on defense, how is he going to help? That's what he has to answer to be more than a lottery center. A better Primoz Brezec.
