Any challengers to Kansas?

Kansas has led a charmed life in their streak of Big 12 championships. It is just unlikely that a program would go that long and not have key injuries or off-court issues that would derail them, at least for one season. Are there programs that could challenge the Jayhawks dominance? In the Big12?! Of course! Lots of them. Kansas State is showing life. Beard has things going at Tech. West Virginia is always tough. Jamie Dixon is building a machine at TCU. And so on. Certainly there are teams that could challenge Kansas. But so far they are still on top. Amazingly.
