You’d typically think the busiest time of year at a football stadium is football season. Not so for Empower Field at Mile High over the past several months. For all the commotion between a Nathaniel Hackett-led September win against Houston and a Jerry Rosburg-led early January win against the Los Angeles Chargers, that was all just a warmup for the frenetic offseason. When the Walton-Penner Family Ownership Group took over the franchise in August, one of the primary questions surrounding its purchase was the future of Empower Field. The owners are still determining whether they want to build a new stadium to serve as the franchise’s home, one thing they knew for certain was that they wanted to update the current one. In late 2022, the club decided on $100-plus million in upgrades to serve as Empower Field’s second act after a 22-year opening run. The challenge: Get it done in eight months. “My challenge to them was that we haven’t touched the stadium in any meaningful way since it’s been built,” CEO Greg Penner said at the beginning of training camp.
