By my count, there are 26 HC changes listed in this story. Not sure if all are D-I, so maybe 26 isn't accurate.
This is probably not all for the season. Who knows? Maybe coaches of some of those 6-6 "bowl-eligible" teams will jettison their coaches when they lose in the FarmFresh Egg Bowl.
Add in the rumor of Saban to the Browns if Cleveland hires Michael Lombardi and possibly another CFB coach or two heading to the NFL after that season ends, and BOB has a great start on the approximate 900 changes Joe saw.
Just wanted to offer another topic besides "Nits vs. no Nits" . . . .
