Yes, I understand Vlade made the decision to extend the coaches.
I don't understand why he would have Williams finish off the contracts. That would seem like an oversight on Vlade's part to have public enemy #1 (Williams) present the Coaches with their contract paperwork.
Maybe Vlade was trying to help mend fences by having Williams be the bearer of good news to the coaches? I don't know, but the coaches sure didn't seem to like it.
Either way, I can see Williams leaving on his own accord this summer. There is too much heat for him and I'm sure there are a lot of teams that would offer him a comparable job.
