You certainly can't fault his performance tonight. I think I liked a couple of things best: first, the way he was pointing out the open man to KT, although it didn't work out; second, the way he called the team together and had a bit of a team huddle on the court; third, the way he was seriously talking to Cisco as they came out of a commercial break.
What I liked the best, however, was the look on Paul Pierce's face whenever he looked up and saw Ron's face, which he did all night.
