As another poster said, the Big 12 coaching staffs are crazy good. All of the following coaches have reached a Final Four or Elite 8:
Self
Drew
Beard
Weber
Kruger
Huggins
Smart
Dixon
Boyton and Prohm haven’t been passed the Sweet 16. With the talent influx at Okie State for next year (including the #1 overall recruit), Prohm might be the lone wolf to not make it to the 2nd weekend of the Dance. I do think Prohm is a great guy and a good coach, but I don’t think there is a conference top to bottom with as many great coaches as the Big 12 and this is why I think it’s a struggle.
