How the John Elway-led Broncos of the mid-2010s grew an NFL general manager tree

The article discusses how the Denver Broncos, led by former quarterback John Elway, became a breeding ground for NFL general managers during the mid-2010s. Under Elway's leadership as the Broncos' general manager, the team won a Super Bowl in 2015, and several of Elway's employees went on to become general managers themselves. The article highlights that four current NFL general managers and two former GMs were part of Elway's staff in Denver. These include George Paton (Minnesota Vikings), Martin Mayhew (San Francisco 49ers), Dave Ziegler (Las Vegas Raiders), and Ryan Poles (Chicago Bears), as well as former GMs in John Dorsey (Cleveland Browns) and Brian Xanders (Detroit Lions). The article suggests that Elway's success in building a championship-caliber team in Denver, coupled with his ability to identify and develop talent, contributed to the Broncos becoming a hub for future general managers in the NFL.
