I don't think the game was as competitive as you think in a double over time game.
Broncos got so many breaks it isn't even funny. Two touchdowns on returns? That's like being spotted 14 points.
Ravens drove, worked for yards, scored, Broncos answer with returning back a kick.
Most teams would have crumbled after that sort of luck.
Bronco was lucky to be in one overtime, nevermind two
