There are reasons I don’t completely resent Bill Callahan. One of them is the beatings which his teams laid on Kansas State, and more importantly, Coach Ron Prince and quarterback Josh Freeman who reneged on his original commitment to the Huskers amid rumors of some shady dealings. Bo Pelini added another Freeman thrashing in 2008 which saw him so ineffectual, he was pulled early in the second half. (The Huskers did have a habit of standing on business when Elite 11 QB’s decommitted - see also Gabbert, Blaine.)
The other reason happened on November 25, 2005, a Black Friday tilt which saw the 14-point underdog Huskers blow Colorado off the field - and some of their fans out of the stands, literally - by a score of 30-3.
