They were 12-1, they lost the national championship game by a wide margin and that's that. Comparing them to 1973 and 1988 teams that DID win the national championship.... I don't see the point of that. Nobody else is making that comparison.
Your post wasn't that bad. The one that made me laugh was the original post in this thread which began with the nutty premise of excluding 2012. Wait, what? You can do that? That sounds as silly as saying "Excluding the 2nd half of 2014, BK has had two national championship contending teams in 5 years."
