I can't think of any real positives to staying in the Big12.
I would argue that our current recruiting classes would be much worse if we weren't in the SEC. Being in this conference has given us much more media coverage. Recruits want to play here due to our conference affiliation, I think a vast majority would overlook us if we were in the Big 12.
I think we fit culturally much better with the SEC. The "A&M's a cult" rhetoric was prevalent in the Big 12, but in the SEC we just seem normal. With the exception of the Lone Star Showdown and maybe OU, I'm much more excited to talk about every single conference game we play here. We can see the grove, cowbells, war eagle....so many more meaningful teams with tradition. Not just me, but the media loves to talk that stuff up, which also gives us more exposure. I mean, what TV network really wants to hype up away games to Waco and Iowa State....I was a student during the Big 12 era and I cannot think of anything interesting to talk up about hardly any of those schools.
There is no reason we won't be a consistent top SEC team soon, and Jimbo very possibly is the right guy to get us there. It's only his second year, he's redshirting most the guys he recruited, his first 2 schedules were nightmares, we lost our TE and RB right out of the gate. If we didn't look so gross against Arkansas (which can happen, especially when the focus are on all these top 10 teams we play) I don't think everyone would be having such a meltdown. We've lost to two #1's and a top 10. In theory, only 10 teams should expect to walk away with any of those wins.
I'd much rather take a few losses in high profile games than sneak in the playoffs by avoiding any competition, that just seems cheap....plus you'd likely just end up losing to some SEC team when you get there.
