I'm not exactly a James Franklin fan, and to an extent, don't like him. But I like to think I can be level headed enough to avoid blind bias. He will not bolt for the NFL, more likely it will be to a bigger college program. If he brings VU into another 9-3+ season and wins another bowl game, he may be seen as a hot commodity. Some major program seeing only marginal or worse success. There's no question that JF is a very good motivator. Like it or not, the guy can coach. Except maybe the desperate NY Jets, I can't see a NFL wanting him as a HC. I doubt VU is willing to shell out the type of bucks it would take to keep him when other programs come calling.
Les Miles? Maybe. He's unhappy with SEC scheduling as it makes it harder work for him to win NCs. I'm not sure he'd be coveted as a NFL HC but maybe an assistant HC. He's just too eccentric to be taken seriously by pro players or even management to be head honcho. Plus I really don't think he's as stupid as he acts. He knows he's in a talent rich state so will field competitive teams year after year, even in down years. If he leaves it will be to another program situated in another talent rich state. My prediction is Mack Brown will underachieve again and be let go by Texas. Les Miles will most likely bolt for Texas. Crazy as it sound, Mack Brown could end up in Tennessee on Jones' staff. [So it is written, so it shall be.]
Franklin is already A hot commodity. He's been an NFL assistant, he can always go do that again. He's been offered the arkansas and NC State jobs, he turned them down. Vandy is paying him big bucks and building the facility's he's asked for. Franklin has A job at Vandy for as long as he wants it.
