If you absolutely had to win a game which Coach would you want on the sideline?

[Clutch]

George Allen, the man could turn a team of losers into winners overnight.

Of the choices listed, Bill Walsh - one of the greatest football minds, and he was always so well prepared. The one slight drawback for Walsh is that he wasn't as emotional a coach as some others like Lombardi, so for a single game having a coach who can press the right buttons to fire up his players might be advantageous - Walsh could do this well for the long haul, for a single game someone like Lombardi might be much better - but I'll still go with Walsh for his football mind and preparedness.
