I like Roy Williams but he completely blew this game against Dook.
He sat Joel Berry, who picked up his 4th foul with 14:30 left in the second half (after a ridiculous call in another game shockingly called all in dook's favor) waaaaaay too long when everyone could see the wheels had fallen off without him on the court. He didn't get back in until 4:30 left in the game with Carolina down 9.
Uh... you don't wait any more once a 13 point lead has evaporated. If you did, then you certainly don't wait for a now-tie game to be pushed to a 9 point Dook lead. What the hell was he thinking? What was he saving Berry for? By that point Berry was cold and the game was over.
I'd rather have gotten 5 solid minutes out of Berry from the 9 minute mark to the 4 minute mark, preserving the lead, and then have him fouled out rather than have him play the last 5 minutes, inserted cold into a game down 9.
