SEC Bias

I've been seeing a lot of boards/media personalities mention SEC bias in the polls. Clearly, I do not agree, but does anyone think that conferences, specifically the PAC-12, are actually stronger than the rankings their teams have? If you like at the BIG 10 outside of Mich and OSU, they are pretty awful. Outside of Georgia even the SEC hasn't looked very dominant. Initially I was against a 12-team playoff but I think this year justifies the expansion. Just wanted to see what you guys think.
