This is something a lot of people don't know. I was watching a YouTube video of the 1991 Saints playing against the Oakland Raiders on Monday Night Football. The Raiders had never lost on MNF. We won 27-0. Towards the end of the game, Frank Gifford was comparing Walsh to Hebert since Hebert was making his return after being out with an injury for several weeks with them loosing all the games in the 4th quarter under Walsh as qb. He put up a stat showing Bobby as a starter was undefeated 12-0 against AFC teams which was unheard of. I thought that was pretty impressive.
