I've answered those questions about Solich a million times. Especially the one about him "only" getting an offer from Ohio, that's been dispensed with pretty thoroughly. Mostly it was about age. Similar reasons prevented Milt Tenopir from working again, even though he was a great OL coach...(and even though many Frank haters think MT was scapegoated by Frank and still had good years left).
Really? Frank wasn't much older than Art Briles is right now and I guarantee Art could easily get a better job if he really wanted it. Joe Paterno and Bobby Bowden coached into their late 70's and early 80's. Steve Spurrier is 68 right now - you don't think he could get another BCS job if he left South Carolina at the end of this season?
Maybe you just can't get the homeritis out of your eyes enough to see or admit to yourself that Frank is not thought of as an elite head coach by anyone other than Nebraska fans. It's alright to admit you're wrong.
