You know what it means

Don't take it in the literal sense that you don't need offense to actually win

Of course you do. However someone has to stop someone to win the game.

The Ravens did it when the Niners were on the 5

The Seahawks did..pretty much all game.

If offense wins then the Broncos having set records, been unstoppable and the best Offense in history should have won easily.

Yet the best Defense in the league was the team who won.

With an Offense ranked in the 20's or low 20's.

Peyton was shut down because of Seattle's defense not because Denver's offense
