Blaahvins sucked, he wasn't anywhere close to good. Not too many UK players i will say that about but he had zero business being anything other than a walkon at UK.
I guess that depends on your definition of good, but he lit up the high school ranks in Kentucky, and he played at UK. That in itself makes him good, like in the top 1% of players nationwide. Of course, he wouldn't have played or even gotten a scholarship if Cal had been here then. He probably wasn't really good enough to play at UK, but there are a lot of good players that aren't good enough.
