I saw most of the second half, but that's really not enough to make any real judgments about the teams. Some things that stood out to me-
Mbakwe- Really impressed me with his athleticism
Hollins- was the pleasant surprise for me, he had a couple plays that showed more athleticism than I though he had, certainly looked taller than the initial 6'3 report, and had a really nice display of ballhandling on one play.
Walker- Really needs to lose weight, but uses his size well and has a soft touch. If his explosion off the floor improves as his weight drops he could be a really nice player. Watching his full court press attempt was entertaining, he certainly played hard.
