I'm the coach of the Texas A&M that backed into the NC game and I agree that teams who lose their CC game should not be allowed into the NC game unless there is just NOBODY else worthy. However, a mid-major that never faced even one top-25 team doesn't deserve a shot either.
Let's compare the teams in the top 8. Texas A&M beat 6 teams ranked higher than 33. Miami (FLA) beat 3, Nebraska beat 5, LSU beat 5, Oklahoma beat 4, Florida St beat 4, and Michigan beat 4 teams ranked higher than 33. Miami (OH) beat 0 teams ranked higher than 33. All losses suffered by the other 7 teams in the top 8 were to teams ranked 20th or better.
I personally think Nebraska should've taken my place in the NC game. In the Big XII, OU beat Nebraska, A&M beat OU, and Nebraska then beat A&M in the CC game. In my opinoin, since Nebraska's loss to OU was so long ago and they went on to beat A&M in the CC game, they should head to the NC game. It's obvious that one of us belongs in the NC game; I just think WIS chose the wrong one.
I can't say for certain who the other team should be in the NC game, butit should definitely be one that's proven already that it is capable of beating top-tier competition.
