Looking at it from another angle, it would be a huge gamble for Fulmer. He's walking into a decent foundation but it's still a lot of rebuilding to do, and that's not something Fulmer is known for, nor has he ever really had to do. He's been out of the game 4 years and the SEC has gotten stronger since then. Right now he's in a good place; he'll always be remembered as the coach that got us an NC and while the fanbase was divided when he left, most still have overall a good feeling about him.
He comes back and doesn't get it done, oh brother. Those pointing to Snyder at KSU, Snyder's first 2 seasons back at KSU were 6-6 and 7-6. After the last 4 seasons, does ANYONE honestly think if Fulmer had 2 years like that things would be ok? Heck no.
IMHO, going back to Fulmer is basically admitting we want to stay in the past and admire our "glory days". I have little faith Fulmer can compete in today's SEC.
