I think you are going a bit overboard to say it is "smoke and mirrors" based on statistics against three really good offenses the last three seasons and an inspired OU in the Sugar Bowl a few years back.
If you look at it in context there are not many defenses in modern football that stop great offenses consistently due to the rules of the game that favor offensive separation and protecting the QB. But Bama is consistent with their game plan and their scheme and it makes them tough to beat in crunch time without epic performances by teams/individuals.
You think that has to do with 'bama or the fact that an overrated Texas, Michigan St or LSU team was facing them? Seems like the CFP is starting to get the right teams in despite SEC bias.
But some of you MF's still wanna run the damn I-formation around here. SMH
