And second, he is one of the top 30, yes 30, coaches in the NCAA. Why do I say that? Because KU is like OU in football, it is MUCH easier to recruit at KU in bball than all but about 3 other schools. If Self was at OSU, he definitely would not be able to recruit at the level he does AND with the ease he does at KU. So, he would have OSU at a better place but no better than old Sutton did. That is why he won't leave KU. He gets in every single door with recruits he wants and when he brings them for a recruiting trip there are 16,200 butts in every seat.
There are 30 other coaches, at least, if you put them at KU that would be doing as well as he is. It is MUCH easier to be a "great" coach at a school like KU.
