Texas would be a mistake IMO. Sarkisian can recruit but he didn't win at Washington, he was a mess at USC, he was bad with the Falcons and got fired from there and then went to Alabama and had all the players someone could ever ask for. Texas' brand isn't great right now, they were 5-7 last year, and they aren't going to be super patient. Lots of potential for turmoil and turnover not to mention unnecessary abuse playing behind a lesser o-line. Why put up with that when you can call any school in the country and call your shot?
Georgia would make a lot of sense to me apart from Stetson Bennett. Manning is probably better than him but I'd be surprised if they kicked him to the curb after winning the first National Championship in a generation.
