How has Peyton Manning changed the game?
Run 5 plays no-huddle from the Shotgun constantly? The Bills did that 25 years ago.
"Call his own plays" (which was more of a 2-minute playsheet), not only does every QB do that, but QBs have been calling their own plays since the beginning of football.
Audibled at the line? Again, same thing.
Thrown TDs from the 1 yard line?
Made going one-and-done in the playoffs ok?
I'm really curious. I think Brady is the best QB to ever lace 'em up, but it would be ridiculous to say "he changed the game".
Unless they're talking about literally "changing the game" as in changing the rules, that's Polian and Dungy, that's not Manning.
