Too early to tell but I think coaches like Grant McCasland, Anthony Grant, and Kim English will be in the conversation. Then there are others that have had success in the MVC like Niko Medved or Darian DeVries. Will be an interesting search.
Matt McMahon has an outside shot.
I think to go with Kim English and let him go through some growing pains, but give him a shot. You would rather have him on your bench than have a Frank Haith with a huge contract weighing you down in a few years when his name becomes a hot commodity.
Watching what Drew Valetine has done with Loyola Chicago and kept the momentum going in the first year as head coach, Mizzou should look at him. His teams play fast, play great defense and play for each other.
