Despite being an a former Cornhusker player, I've heard that Frost is more likely to end up at Florida than Nebraska. Times have changed; will be very hard for even the best coach to win big at Nebraska now. There is just no local recruiting base, and there are a ton of other schools that kids from California, Texas and Florida would rather go to now.
Comparing Clawson to Elrod even among the TN lunatic fringe is ridiculous (Elrod schemed to destroy the WF Football program; that's just another level from a perception of being an inadequate OC), but agree Clawson is very unlikely to have even remote interest in the TN job, he was eager to leave Knoxville when he was their OC, and their fanbase is more delusional than most in the SEC (which is saying something).
Agree that Clawson feels comfortable and happy at WF, but his stock has never been higher and there is stupid money available from desperate Power V programs. So, I would be surprised, but not shocked if he flirted/considered a high dollar/long guarantee offer from a Arkansas, Texas A&M, LSU, maybe even Nebraska type of school.
