I saw a few people bring up Saban as a joke. Just in case you aren't joking, I would like to remind everyone that Saban's successes mostly came from the pre-NIL days, and that he probably recognized his abilities were diminishing with age, to a point where he was not realistically able to meet the high standard he has set for himself.
He would certainly be past his prime, by his own admission, and while that still could mean he would have winning records at almost any program in the country, it doesn't necessarily mean he would do better than 9-3 in the SEC as HC of Texas. How dumb would we look if we spent all that money getting him and then had to spend a lot of money buying him out? Might not end up as much of a trainwreck as Bellichick, but it still wouldn't be our standard nor anywhere near worth the money spent on Saban.
For my money, the best option is Marcus Freeman. He has a track record of recent success at a blueblood program, he's young and energetic, has media savvy, and there doesn't seem to be much in the way of off-field distractions.
I would stay far the fuck away from G5 fools gold, especially Traylor.
