Vandy has an easy schedule now and they have had an easy schedule for the past two seasons. Once, they get a more difficult schedule and Franklin sees that he can't keep getting winning records and bowl games, he will leave for a different job.
His stock will only rise as long as he is winning. Once a more difficult schedule arrives, they will start to lose and his stock will begin to fall. He will bail before he starts to lose.
Kinda like Urban Crier did once Tebow left..... He jumped ship and left his replacement with an empty cupport of players and a losing record. Franklin will leave soon enough.
