Danny White will make sure he's paid what it takes to keep CJH. They have a long history together. Nobody has a better fan base and facilities than UT and recruiting won't be a problem now that the program is on the rise. Coaching in the NFL much more difficult and stressful. Saban, Spurrier and Urban couldn't hack it. CJH stays a VOL for a LONG TIME.
I agree with everything you say, but people are quick to forget Barry Switzer, Pete Carroll, Jimmy Johnson, and to an extent maybe Kingsbury. Granted, some of those guys are from a different era, but it has been done. I do think that with Saban, Spurrier, and Meyer it was their arrogance that led them to the NFL, I don't see that in Heupel. I hope he's here for a long time.
