Texas is a better fit in the B1G, but that's not going to happen. They were perfect in the Big 12/SWC, but those programs don't turn on TV sets, and recruits straight up told the Texas brass, "Ya'll got an awesome program! I'd love to go here, but the SEC puts players in the League.". Mock the S-E-C chants all you like, Lord knows I do, but the kids go where they can get seen and get drafted.
Texas had to move, and the SEC made the deal. Now that NIL makes paying players not only legal but highly encouraged, Texas should be a good fit.
