I started to realize it this past week, but tonight solidified it for me: we just aren't an elite team and not having a good inside presence is the biggest reason. While Niang is certainly missed, I would say this team misses McKay more, or a player like McKay.
That said, I still like our chances to make the tournament, provided we get to 10-8 and win 1 in the Big 12 tournament. And I think that's entirely possible.
I also am nowhere close to saying Prohm is not a good coach or the right coach. He still has my support.
