I'm almost shocked that Danny was going to use the mid level on Cousins. The guy won't be ready to play until mid season, and he might not be 100% this season from that injury.
My guess is this is a war between GS and Boston. Which now are supposed to be the top 2 teams. If that's the case, I would not be shocked if Ainge went after Howard, as others here have suggested. Howard had a surprisingly good year in Charlotte. Very durable. Lots of the usual stats for a dominating center. But he doesn't shoot the 3--whatever that means.
Baynes is a nice player for toughness, but he doesn't match up well against the real bigs. He plays lateral D, not vertical D. Williams is a vertical guy, but it looks like he may have trouble showing up for games, at the rate he is going. Plus he lacks the experience to be a contributor right now. I have to see some hesitation in Danny growing about that.
So maybe he makes a pitch for Howard.
