Looking at the whole thing, the only better thing he got at A&M was more money and maybe more control. The school is obviously willing to pay whatever it takes to play. But in almost every other statistic that job was a step down. Harder schedule, the school has less of a national name, harder recruiting battles, etc... It would have been one thing to take the job at Texas, but going to A&M just shows that this was more about his relationships souring here than it was about being a better opportunity.
In the end I think he'll be an upgrade, and maybe they make it to one or two SEC Championship games with him, but there's no way he ever gets them anywhere near a National Title. Truth be told, I'd come to that conclusion here. Every year had been a step down since Jameis first year. That year we happened to have just recruited an NFL defense and had Jameis at QB. We won in spite of his coaching and because of his recruiting. He hasn't hit that lightning in a bottle since.
