I think it has leveled out some more since NIL and the portal. However, I think it is just far more apparent that they HUGE HYPE about the SEC is only hype. Sanky and ESPN try to push that every single SEC team is equivalent to an NFL team, and every other team, except for a few Big10 teams are equivalent to D2 or high school teams. It has never been that big of a spread. In the perception of the ESPN commentators, beating Miss State is a huge deal because they are an SEC team. Beating Duke is not significant because they are just an ACC team, even though they went 9-3 this year.
The SEC receives a lot of credit for winning most of the BCS games. However, the SEC was at least 1 of 2 teams in the BCS most years. They were every single year from 2006-2013. In the 2011 season, the both teams were SEC teams. The SEC was guaranteed to win the championship after the last BCS rankings. I think that the SEC saw that hype would increase rankings, and ensure that the SEC was included in the championship. The SEC has hyped so much that the committee last year was afraid to leave Alabama out, and they moved Texas up several spots so that they could them move Alabama up to number 4.
I am certain that Sanky and other leaders of the SEC know that they are only spewing hype. They change the hype every year. Some years, big wins are more important than bad losses. Other years, bad losses obviously are more important than big wins. Their statements aren't rooted in truth, they are crafted to get a desired result regardless of what they actually think to be true. Some people are making fun of Sanky's statements from the last few weeks. But I predict that in the spring, and then summer Sanky will be touting the SEC again, and ESPN will be pushing the SEC narrative. By the summer ESPN will have people believing that Alabama, mutts, Ole Miss, LSU, Florida, etc. are made up of players that can chew steel, run faster than flash, and could handle the 1985 Bears like they were herding sheep.
