I think, at least from the stand point as to why the SEC hates us so much (I live in Georgia), it's because many times, especially in the last 10 years or so, Ohio State has or has had the chance to stand in the way of the SEC's Success.
Meyer had to lobby to get his Gators in to the 2006 NCG. I don't think that Florida was that much superior to us. I just believe they prepared better for the game and it showed. All season long the Buckeyes heard about how good they were and how no one could beat them. They already took down two #2's, what was one more?
In the 2007 NCG, Ohio State had an opportunity to beat LSU, but they lost it when they quit running Wells (sounds familiar). Wells was racking up yards until we fell behind and I think Tressel panicked and decided to start throwing the ball more. Stupid penalties gave LSU first downs on drives they had them stopped and then LSU would move the ball down the field and put points on the board. The Buckeyes tried to play too hard to prove that they could play against the SEC and it cost them.
SEC county then decided that Ohio State was inferior to them and in combination the B1G because Ohio State basically ran the conference at that point.
After the 2010 season and Ohio State was slated to play Arkansas in the Sugar bowl, Everyone I knew was saying how bad the Razorbacks were going to kick our butts, but when that didn't happen. They turned to well "Ohio State blew a huge lead and nearly lost", or "Arkansas isn't a traditional power in the SEC so you really didn't beat a good SEC team"!! This win also ended the winless streak against SEC opponents in bowl games. Of course, that didn't last long with the NCAA vacating the win. And because of the "scandal", it lead many SEC fans to believe that the only way Ohio State could hang with them was by "cheating".
The Gator bowl following the 2011 season wasn't really success for either team, but the fact that even while both teams were lousy, the Gators were able come away victorious!
Now on to the 2012 season. The Buckeyes go undefeated, as does Notre Dame. If Ohio State were not on a bowl ban, It would have been tOSU vs ND in the NCG. Which in turn would have left Alabama out of the NCG, and last season would not have ended with Alabama winning it's second straight national title and the beginning of this season starting with them going for their third.
So here we are, 2013. Ohio State 12-0 going to play in the B1G championship game, and with a win it had the potential to keep the SEC out of the championship game again. However, that did not occur and here we are with Auburn going to play FSU. the SEC going for it's 8th straight title and the state of Alabama going for it's 5th straight. (sigh...)
The conference's record in bowl games and in OCC games against other BCS conference schools has not helped either. I agree with the comparison to Oklahoma. I have asked several times why they aren't as scrutinized as the Buckeyes and I rarely got an answer. I'm still clueless as to how they got the "at large" bid in to the Sugar Bowl.
