It's strange that Stoops thinks the SEC is overrated when his supposedly elite Big 12 team got stomped by a new SEC team in the Cotton Bowl 42-13. A&M was much tougher than Stoops expected because the schedule (and a better coach) hardened that team, which was basically the 3rd best team in the SEC based on record and performance by the end of the season.
In the Stoops era which started with the 1999 season, Oklahoma has a 3-4 record against the SEC. With a couple of those wins coming against middle tier (at the time) SEC teams.
