With the length and size that also has major quickess in the 6'7-6'9 range, if Kentucky doesn't show to be a pretty good team playing defense, this might be the year the NCAA finds something on Cal they can use to kick him out of college basketball. If these guys can't play defense, Cal might just go Bobby Knight on the court. These kids seem to be good kids and none are really known as the type of kids that play lazy on the court and need to play harder. Diallo should be a monster on defense, as long as he shows the want to part. I think at the least Diallo shows average defense. Green might sometimes have trouble on defense while playing bigger guards, but even that won't happen often. The Mark Jackson backing down a smaller guy in the post offense doesn't seem ever happen in today's college basketball world.
