I just don't understand this level of disdain at all. It is pretty clear by now that we were turned down by (and/or had almost no shot with) almost all of our top choices. Given that fact, why are you "absolutely embarrassed" by this hire? I agree the contract details and staff will matter, but we don't even know those details yet. I don't see Pastner as discernibly different from Cuonzo or Capel. All guys can recruit but have at least some significant question marks concerning coaching.
Do you really believe the other options we were left with (Kelsey, McCall, Keatts) are unquestionably better hires than Pastner? I certainly don't. I think Pastner has already shown a higher ceiling than what any of those guys have shown. Pastner has some more negatives, but some of that could be due to the fact that the other guys basically still have no real track record. Heck, look at Gregory's first two years as a head coach and compare it to those guys. Looks pretty similar (if not better) to me.
Here is the question for anybody who is "embarrassed" by this hire: who are the guys we should have gone after but didn't who were clearly so much better options (with the stipulation that it must have been reasonably likely they would have accepted an offer)? If you can't answer that, I can't help you.
