Good thread HR, very helpful, this year will be the biggest mess, yet, coaches moving, and players will opt out for NFL more than ever.
A KEY to look for is when an OC leaves, one that called the plays.
Eg, a few yrs ago Missouri OC left along with his OL coach who was the backup for calling plays, a low level asst called the bowl offense plays against Texas, the head coach at the time was a defensive guy his whole life. Missouri got smoked. Similar thing happened at SMU several years ago, too. There have been others...
Similar with DC's but not as impactful.
