NO NFL head coach has ever won a Super Bowl with one team, and then gone on to win one with another team. Never ever in the history of the league. Not Lombardi, not Parcells, not Holmgren, not Seifert, not Reeves, not Jimmy Johnson.
All you Gruden and Cowher lovers remember that. Also remember that Gruden and Cowher each only got their teams to ONE Super Bowl.
Cowher lost to the Cowboys in the 90s, and then won a Super Bowl against the Seahawks.
If it weren't for the Tuck Rule, Gruden likely would have been to two Super Bowls.
Marv Levy lost 4 straight Super Bowls. Would you have fired him after the second because he couldn't possibly have won after two straight losses?
The idea that it's never possible for a coach to win a Super Bowl with two different teams is laughable. Just because something hasn't happened yet doesn't mean it won't. No team has ever won 3 straight Super Bowls; does that mean it will never happen?
