Who Would Win If the Dallas Cowboys Dynasty of the 90s faced the Colts Big Three of the 2000s in the Super Bowl?

Emmitt Smith and that offensive line would have a field day with an average Colts defense.

Pretty much this. The only chance the Colts would have would be for the game to turn into a shootout. I don't see that happening.
I see Dallas winning with time consuming drives and wearing that Colts defense down by the 3rd quarter.
