Why not look at the entire schedule and the wins? The SEC is very top heavy lately and not near as good as most will try to convince you it is.
OK show me what wins on OSU's schedule from 2011 deserved a lot of recognition? 4-5 Texas / Texas A&M games? OU without ryan broyles? You could argue the only win worth noting on their whole schedule is the KState game. And the national perception of KState hasn't been that high until this year.
Alabama's only big notable wins were against Arkansas and Penn State. The rest were nothing special.
I read your last statement from too many places too often. YES the SEC has been top heavy the last few years. Someone please tell me a conference that HASN'T been top heavy in the same time span.
ACC/BigEast - not even up for discussion
B1G - Wisconsin, OSU, and I guess you can include MSU. But only one of these each year has been elite, the other two above average and then a bunch of run of the mill teams with a couple doormats
B12 - 1 elite team from the south each year that will prob lose it's BCS matchup. couple 8-10 win teams. lots of .500 or worse
Pac12 - Oregon and Stanford. That's it. the bottom of this conference is heavier than the other 3 in discussion. Their run of the mill teams are below average in comparison
SEC - Find me a recent year where SEC doesn't have at least 3 teams that can play with the top team in another conference.
