He's fine. This league has so many good coaches, it's really hard to rank them.
I would say 6th or 7th, but as you said, there are a lot of good and great coaches in the Big 12. We like to make fun of Drew and Weber, but the results are there. Self might be the best coach in the country. Dixon was a great find, and Kruger has done so well at so many places it is hard to discount him. Huggins, I never liked as a coach, but he has always had teams that would terrorize teams into mistakes without ever getting into foul trouble, so I guess that is coaching.
Prohm had a very young team this year, and it is showing now. Other teams have seen all the starters and figured out which way they like to go, where they take shots, etc. Shayok has all but disappeared for the last couple weeks. Young guys rarely come into a program with the level of conditioning needed to play major minutes for a whole season. Wigginton was hurt, Babs is always hurt, Lard is just not a guy you are going to be able to count on for consistent play. The loss of Young in the post for defense and rebounding is something we don't think about a lot, but he could have made a difference is several games when Jacobson was being abused and Lard was just fouling.
