college basketball is seriously weak right now...if you can't see that...then i don't know what to tell you..
because of the one and done rule. it isn't just weak for no apparent reason, the one and done rule is causing it. but the same rules apply to everyone, so it is a level playing field. It isn't like Duke dominated a weak field season of college basketball. If we had dominated a weak field, then you could say well that team played in a terrible year, which is why they were so good. No one last season dominated, and no one will this season either.
It isn't that there is a lack of talent, it is that the talent is so spread out now. The one and done rule SHOULD be hurting the traditionally top teams, but Kansas and Duke have a much better recruiting strategy in terms of dealing with it then other teams to. You could also throw OSU in there. Kentucky's strategy only works because they get like 5 one and dones a season...
