Here’s how the various stats correlate to Winning %:
Difference between offensive TD Scored and Defensive TD allowed: .90 (of course)
Offensive TD per 16 games: .67
Defensive TD allowed per 16 games: .54
Total TD per 16 games: .17

I personally don’t go that far, but I hate when people try to gloss over Seifert as being a Jon Gruden, a man who won with another coaches players. First, he coached a lot of those players too, and he stayed long enough and win enough that he has his own resume that holds up.

Honestly, if Roger Craig doesn’t fumble against the Giants in 1990 and they beat the Bills and three-peat, he probably never gets ‘let go’ from San Francisco after ’96 and is an easy Hall of Fame coach today.
