ENGLEWOOD, Colo. -- The Denver Broncos rolled through their offseason work and into summer's training camp with a feeling that the talent at the top of their depth chart was good.
Good enough to compete with the league's heavyweights on the team's best days, good enough to rebound from a 5-11 finish in 2017 and a 6-10 finish in 2018.
But a lack of depth left them vulnerable should injuries occur and now their house of cards has begun to topple.
Linebacker Bradley Chubb's season-ending knee injury announced Monday is the latest, and biggest piece of injury news the 0-4 Broncos have encountered in the season's first month.
