The absolutely worst game I ever witnessed live was the homecoming game in Callahan's last year, when the Huskers were down 35-0 at halftime. Adding insult to injury, it was the 10 year anniversary of the 1997 National Championship, so the entire '97 Husker squad was standing on the sidelines watching Callahan smile and doodle on his clipboard.
That was absolutely the most horrendous game I have ever seen. Then to top it all off, at the press conference after the game, Callahan took no responsibility whatsoever, and actually had the gall to look the reporters in the eye and say, "The system works!"
The only thing that worked with Callahan at Nebraska was the hammer that Tom Osborne brought down after the season was over.
