Unfortunately, there are some Buckeye fans who hear "strong recruiting class" and think Kentucky. This group is not like that and most programs can't do what UK is doing on consistent basis anyway. Plus, if you look at Calipari it looks like the pressure is killing him.
Truthfully, Matta had three bad recruiting cycles - the outgoing seniors, the Amadeo class, and the Loving class. He deserves criticism for that. I would say that Craft and Lenzelle did improve in many ways during their careers, just not as shooters. But they were complementary pieces in that class anyway. The problem was that all of the next three classes turned out to be complementary pieces, if that. It's hard to win with a group like that, which is why the last two seasons have been a struggle.
Losing DAR hurts, but Tate showed real fire last season and KBD could be a very skilled player. The new group appears to have a lot of upside along with Thompsond and Bell. We should all remember that, aside from Trevor Thompson though, not one of them has played a college game. They will likely not be like the freshmen Kentucky trots out. They will probably be more like the IU team when Cody Zeller was a freshman - some good wins with some very frustrating losses. I say that with the caveat that Matts > Crean.
Those growing pains should lead to a very good team in 2016-17 though.
