I agree with your assessment, although I don't agree that he will coach again as a "head man." Certainly not at any school of consequence.
I wouldn't necessarily agree with you on this one. I don't know how desirable Jones is. He doesn't seem to have the same membership to the coaches club as a lot of guys. I imagine his opportunities for this year were somewhat limited. That said, he obviously had the luxury of being selective, and I can't blame him. If I was getting paid to not work, I certainly would be choosy about the next job I took. I would make sure it was a place that I was pretty confident that I had every opportunity to be successful. Further, if I aspired to be a successful head football coach, I would be pretty interested in looking into how things work at Alabama under Saban. I am guessing Jones thinks he might learn something.
I never cease to be amazed by the positions some take. Jones was offered the UT job, and like just about anybody offered a huge opportunity, he took it. He did not fail because he was unwilling. He failed because he was incapable. There's no doubt in my mind that he made every effort to be successful. It just wasn't good enough.
