BOCA RATON, Fla. — The Broncos remain uncertain of their opponent when they open the 2016 season on Sept. 8. One thing is clear. They will acknowledge their championships in front of a sellout crowd. Broncos president Joe Ellis said the team will unveil a banner representing the franchise’s three Super Bowl championship titles.

“We want something more visible and prominent for the fans to see,” Ellis said, noting they were previously displayed in the back of the end zone. “We want to make it a special night.”

The Broncos won back-to-back titles in 1997 and 1998 and ended their championship drought with a 24-10 upset victory over the Carolina Panthers in Super Bowl 50. It capped a season in which the Broncos perfected the art of winning ugly and winning late.

“I thought last year our fans came together with the team on the field and kind of willed our team to victories that in previous years might have gone a different way,” Ellis said. “The most remarkable thing I remember about last season is that (in the AFC title game) when the Patriots scored that (fourth quarter) touchdown and made it a two-point game. A lot of teams’ fans would have had the air go completely out of their balloon. With our fans that never happened. I was down on the field. The crescendo and level of intensity didn’t waver one iota. You could feel their support.”

Global reach. Ellis said the Broncos are pushing to play a future international regular-season game in Mexico City, London or China. It would not come at the expense of a home date. Owner Pat Bowlen advocated expanding the team’s brand with appearances in global games for years. The practice halted when the Broncos signed Peyton Manning, with Ellis receiving input that teams were reluctant to consider an off-site game because they wanted their fans to see Manning.

Put a Ring on it. The Broncos tentatively are scheduled to be honored at the White House in early to mid June for their championship. Around that same time, the Broncos will hold a private ring ceremony to celebrate their Super Bowl 50 title. Ellis is part of a group helping to design the rings.

“It’s been very enjoyable,” he said.
