Seriously, as I saw someone simply say yesterday on the radio, Fred is unemployed and can decide what he wants and has the luxury of not "needing" a job. Heck, Fred started as a young kid in Nebraska so it's fair to say he may have some affinity to them like he did us (with his grandpa coaching, etc). For the same reason Campbell seems to like Ames (the chance to do something special with a team with not much history), Fred could do the same at Nebraskaball.
I think we all need to remember, these folks (coaches, universities, etc) don't always look at this with fan lenses on like us. We like to think that Jamie and Fred hung out at the water cooler making small talk and discussing contracts, but that's not how this works.
I respect Fred, am thankful for his time as a player here, thankful for him turning us around, and wish him the best.
