Seriously, I'd love to see the names you would put forward. If I am wrong, I'll admit it. I doubt you can produce relevant evidence that suggests I am.
And don't bother bringing up names from before let's say 1990 because the two games have really diverge since then. There aren't a lot of guys who have done it and it isn't because of the money (the money didn't stop Lovie Smith from moving to a truly bad program) and the reasons are pretty transparent. It is rare when it is successful.
And just so we stay on point. I am talking about head coaching guys whose primary experience is in the pros and changed to college in the last 25-30 years. Two examples are Carroll and Mora. And both weren't exactly achievers at the pro level (before their moves to college anyway) so saying their college results are better isn't proof of anything.
Just so you understand, I am not worried about hiring a guy like O'Brien who has extensive and relatively recent college experience. I think any head coach at ND has to have somewhere along the line experience as a head coach and if that experience isn't in college he should have been at least a Coordinator at the college level within the last 10 years.
