The quarterback completed 327 passing yards and threw four touchdown passes during the team's fourth victory of the season.
The 37-year-old told reporters: "That's good execution on first and second down. We didn't have penalties, we didn't have mistakes that were putting us in first-and-long, second-and-longs, third-and-longs.
"We had some of those in the first half. You don't have to be in third down if you are doing your job on first and second down.
"Certainly that can put a lot of pressure on a defense, keep them from being able to to their third-down package and substitute. That was good today."
The Broncos face the Dallas Cowboys next week.
