The committee doesn't value a tournament run any more than they do what happens in the regular season. A lot of losses in a row, a lot of wins in a row, and they were left with things like who did those wins come against? Non-con SOS sucks.
@BamaFan334 Michigan's non-con schedule is a lot harder than A&M's as a tie breaker.
