Calipari started from scratch with this year's Arkansas roster too, and is relying more on freshmen. That didn't stop people from screaming "told ya so!" after every loss.
Calipari got the players he wanted. He got most of the recruits he had at UK, plus 3 returning players from UK. He had a top 10 roster at the start of the season and he stripped UK of all its players. WTF are you talking about? He didn’t even have to work for that roster.
Heck, not only that, but he ended up getting Davis, Aidoo and Brazille. He has a better roster right now, then he was going to have at UK this year.
You should be more worried about KU's coach and roster, because it's looking pretty bleak.
