The Broncos have added Peyton Manning and they could now begin the 2012 season in prime time. The team has been informed that there's a strong chance that it will be chosen to kickoff NBC's "Sunday Night Football" slate Sept. 9, according to The Denver Post. The Broncos had two games in prime time last season: a Week 1 game against the Raiders on "Monday Night Football" on ESPN, and a Week 11 tilt against the Jets on NFL Network.
