Never had faith in Callahan. He was, after all, the 4th or 5th choice and was hired in desperation. No Al Saunders, no Houston Nutt (not that Nutt was any good) or any of the others. Callahan was fired from the Raiders after a team mutiny, and Pederson hires him. Never embraced the team tradition. Crap-canned the walk-on program. Fired every good coach we had.
Good coaches mold the team's offense and defense around the players that they have, while trying to recruit the players for the system they eventually want. Not Bill! It's "only one game, only one season" and 40+ years of winning football goes down the drain.
I can't believe the blind faith that people put in him and his program. I've watched Nebraska football since 1960 and lost sleep when he was hired. Pederson was/is a control freak and Callahan is an arrogant moron.
I guess my vote is: when he was hired.
