He spoke to our Gator Club when he was at JU. He's a likable person and I can't imagine an AD sitting across from him and not wanting to hire him.
There are very few coaches that go from where he is (in a lower division) to a D1 job, especially a P5 job. Kleiman at NDSU is about to take K-State, which is 1AA to P5 - a huge move (his previous boss at NDSU took the Wyoming job, a 1AA to G5 move, and Kleiman was elevated to head coach). Chris Hatcher crushed it at VSU and then got the Georgia Southern job, where he was ultimately fired (he's taken 2 other 1AA jobs since: he went to Murray State and now Samford (where he had a losing record at MSU...and 18-15 at GSU - he only won big at VSU). I could see Kerwin getting a 1AA job or taking a OC job at a lower level D1 (like Troy, Southern Miss, UAB). I'm sure he's been offered QB coach gigs at SEC type schools, but he seems content as a head coach at a smaller school. I can't imagine he makes much more than $250K at VSU, so he'd get a big pay bump if he left for a better/bigger job. If he wins the NC at VSU hopefully he gets a job he wants. Otherwise, VSU may be his final stop (he's 53 now, so not young...but not too old to take over another program).
