ENGLEWOOD, Colo. -- As Sean Payton strolled among his players before a recent Denver Broncos practice, he looked like a football coach who had it all. The Broncos' new $175 million, 205,000-square-foot team headquarters, set to open later this month, sparkled in the afternoon sun, and virtually every starter from last season's 14-3 team was back. The team had also added Jaylen Waddle to the receiver corps, further contributing to the good vibes.
