As I suspected, a healthy dose of caution and the desire to work some practices in before letting Hansbrough back in the lineup. Via ACC Now:
"We let Tyler do dummy offense,'' Williams said on the Monday night show, according to insidecarolina.com. "It's the first time he's done anything in three weeks. He did fast break drill No. 1, which is just run down there and shoot a layup and you run back. Then we did dummy offense, trying to make sure he still knows the plays. He dunked about 10 of them, and I took him out, because I said,'Tyler, it's OK to lay it up.' I think he was trying to show me that he's OK. But that's all we let him do."
I am think he sees limited time versus UCSB on Friday night.
