The team that should have been left out was actually Texas. That precedent had been set throughout the modern era, and it's the correct one, if you're looking at schedule strength. They had the lesser loss. Alabama had the better loss.
1993 Florida State gets in over Notre Dame, who beat them, but had a lesser loss to Boston College
2000 Florida State gets in over Miami, who beat them, but had a lesser loss to Washington
2008 Oklahoma gets in over Texas, who beat them, but had a lesser loss to Texas Tech
I'm sure there are more, but that's a different argument - that's the argument between Alabama and Texas.
But back to FSU, who absolutely should have gotten in. We simply don't have enough data to take 'holistic' approaches. Because you matter how you shake it, FSU had the better resume. Again, they got screwed due to losing their QB. PERIOD. Please explain, again, how you look at their schedule above and say "hey, this isn't a playoff team".
