On July 15, 2015, Thomas signed a 5-year, $70 million contract extension with the Broncos, just hours before the deadline for franchise players. The deal was similar in structure to Dez Bryant's contract extension with the Dallas Cowboys. Bryant was also franchise tagged and signed just hours before Thomas. He was also drafted just two picks after Thomas, going 24th overall in the 2010 NFL Draft.  Between Peyton Manning struggling with a plantar fasciitis injury and Brock Osweiler never having a career start before this season, Thomas's production dropped, but he still had 105 receptions, six touchdowns, and 1,304 yards.  The Broncos finished the season 12-4 and earned the #1 seed for the AFC playoffs.  Thomas was also named to the 2016 Pro Bowl but did not attend because of his team's playoff finish, but was still awarded a Pro Bowl berth retroactively.  The Broncos defeated the Pittsburgh Steelers in the Divisional Round and the New England Patriots in the AFC Championship to make it to Super Bowl 50, where they defeated the Carolina Panthers by a score of 24–10 to give Thomas his first Super Bowl title.  Thomas had one catch for eight yards in the Super Bowl.  He was ranked 62nd by his fellow players on the NFL Top 100 Players of 2016.
