Did you watch that game against the Patriots in the playoffs? He also looked like crap in an important division game with the Titans toward the later part of the season. There was also the 2002 week 2 game against Miami, the week 7 2002 game against Pittsburgh, the week 14 2002 game against the Titans, and a relatively bad week 16 game against the Broncos last year.
Limiting this to the Dungy era is really stupid, btw. Are you really trying to suggest that Dave is superior to a guy who made it through 15 seasons? If we're taking coaches into consideration, that has to happen for all involved.
