The only Flood loss that compares is Kent State (went on to be ranked and almost made an at large bcs before a late loss) and that came in a season with 9 wins.
When did Flood have a loss this bad? When did Flood lose 78-0? He had plenty of bad days but at less he won a few games! Here are some teams Flood beat:
Arkansas (x2)
Washington State
Michigan
Indiana (x2)
Maryland
UNC
Kansas
Chris Ash has yet to win a single game against a P5 opponent. He has won one FBS game, barely beating New Mexico.
He suffered perhaps the worst defeat in the history of Big Ten football 78-0, without a first down until the fourth quarter.
Flood was not good and had plenty of lousy days but Ash has a long way to go to sniff his jock, frankly.
