The SEC is a dominant conference, which is obvious because of the last 6 national titles being owned by teams of the SEC, but I don't think that the discrepancy is that large. The SEC has 2 or 3 really good teams each year and the rest of the conference usually isn't anything special. Florida, Vanderbilt, Kentucky, Auburn, Miss St, Tennessee, and Ole Miss were all not that good last season - average at best. Then they had some respectable teams in Georgia and USC who were above average, and then they had the 3 big dogs who were Arkansas, Alabama, and LSU. To me, Arkansas was potent offensively but also very beatable. Texas A&M was winning pretty good through the first half and then collapsed just like they did every game last year in the 2nd half. Alabama and LSU however, were really freakin' awesome, and nobody else in the country was anywhere near their level.
Other than my SEC rant, I actually enjoy ESPN. Not their opinions, just their timely news updates and the resources they have available on their site. It's the first place I go when I need to look up something about a team or player. I just try to ignore the fluff and use the information given by ESPN to form my own opinions, which is what everybody should do IMO.
And I also like listening to Colin Cowherd. And yes, I do expect to take a little heat for that.
