I don't know if it's overrated or not, but the middle of the pack SEC teams get the benefit of the doubt more than they should IMO. Then, when they play similar OOC teams and lose, ESPN acts like it's some huge upset when oftentimes, the OOC team was better to begin with. I think Bama, UGA (healthy), LSU, and aTm can play with anyone. I wouldn't put A&M in that group if it wasn't for Manziel, but he is insane and will keep that team in every game he plays, no matter how bad the defense is. UGA is ripe for the picking right now because of how beat up they are. But even with that, the teams they lost to are a combined 12-0, and they beat the #6 and 11 teams this year. UF has two losses against the #6 and 10 teams, so they are likely in that group as well, especially with the way they play defense. This year, I think there are more challengers to those teams than in years past. Oregon, Stanford, tOSU, FSU, Clemson, and maybe Baylor could all present problems for the SEC top. They would boatrace the bottom 8 teams in the SEC, as would several other teams in the Pac12.
As for this week's poll, I find it amusing that Auburn gets a bump for beating a team that 95% of BCS teams would beat just as bad, while teams like Wisconsin and Michigan get ranked lower. Maybe AU is a top 25 team, but beating W.Carolina doesn't change anything IMO
