I would say that good programs have either been plagued by injuries or recruits not playing to their potential. That is the reason that this season is so up and down.
Duke, with Ryan Kelly, was almost great. Without Ryan Kelly, they have lost three games and at times look no better than average.
Louisville has been dealing with injuries all year; and, R. Smith's shooting slump has not helped.
KU is a six-man team. Perry Ellis has not yet made the transition to college. When Whithey or Young need a rest, KU has to hope to just play even for two or three minutes.
I do think that aside from Duke with Kelly, the best teams this season might all reside in the B1G. However, then IU, Michigan, Michigan State, and tOSU just beat up on each other. I will be very surprised if a B1G team does not win the championship this season.
