What does it take for John Elway to overcome deep personal tragedies to return to the sport he loves? Sports-writer Jason Cole found out.

Cole, who has written about the NFL for more than 35 years for the likes of Bleacher Report, the Miami Herald and Yahoo Sports, talks about what makes Elway unstoppable in his sixth book, “John Elway: A Relentless Life,” the unauthorized biography of the Hall of Fame quarterback, two-time Super Bowl Champion, and now President of Football Operations and General Manager of the Denver Broncos

Cole interviewed more than 200 people over several years, including Elway himself, in what was one of the most exhausting and intense writing experiences of his life.

Cole discusses what happened with John after he retired — when he went through a very dark period — and how he he returned to football at the bottom, and waited more than a decade to return to his beloved Broncos. As Cole describes, Elway’s story is filled with one seemingly unstoppable challenge after another.

You can get a copy of Cole’s book at your favorite bookstore or on Amazon.
