May be an interesting story going forward, with the way programs will treat the new position. Alex Grinch has been very successful at improving what had been a tire fire of a defense. Had Leach gone to Tennessee or anywhere else, the indications seemed to be Grinch would get the head job. He's been mentioned as a potential DC candidate for open jobs in the SEC.
This has the air of the late-90s, early aughts Yankees about it if it happens, getting guys who seem way over-qualified for the job they're going to have.
Also, we haven't heard much about where Michigan might go with the 10th job. When Smith left, the specualtion was about Zordich taking over the entire secondary and perhaps hiring a true WR coach. Maybe JH does go with Bush Sr. and a WR coach. Maybe Chuch Pagano joins his nephew? We'll see.
