2016: The Denver Broncos hosted the 2016 Kickoff Game at Sports Authority Field at Mile High against the Carolina Panthers on September 8, in a Super Bowl 50 rematch. (As the Republican and Democratic conventions were both scheduled for July 2016, there was no scheduling conflict with them as there was in 2008 and 2012, nor were there conflicts with any other sports team in Denver that night.) The Broncos debuted Trevor Siemian as their new starting quarterback after both quarterbacks who started games in 2015 left the team; Peyton Manning (who played the entirety of Super Bowl 50) retired and Brock Osweiler left as a free agent.
