What has a team like Iowa done to validate its argument? Win a big game OOC, nope. Schedule tough OOC, nope. Close out games against top teams in conference, nope.
Look I think Iowa deserves more discussion, but they had plenty of opportunities to get enough wins. A team like MTSU, never gets that chance and if they are the regular season winners, the teams they play put their best effort in to beat them knowing there is no other shot to get to the NCAA tournament.
The other issues I have had with the mid-majors have had to play each other in the tournament as well. I like the idea of the little guys getting the shot, I just always have. Why does one loss in their conference tournament have to ruin their chances as well, when Power Six teams have opportunities to win big games all the time? Peeing games down your leg, or losing close games means you lost games against good teams, just like a mid-major team can.
