ENGLEWOOD, Colo. — The Broncos are poised to enter the 2020 season as a contender in the AFC West.

Though the Kansas City Chiefs are the reigning Super Bowl champions, the Broncos have paired momentum to end last season (a 4-1 finish) with a strong free-agency period. At the very least, a wild-card berth should be an attainable goal for this year's group.

In just over a week, the Broncos will try to put the finishing touches on their roster when they assemble the 2020 draft class.

It is not, however, the 2020 class that has Denver poised for success under Head Coach Vic Fangio. Rather, the combination of the 2018 and 2019 draft classes have built a new foundation for the Broncos.

And, to be certain, a retooled roster was necessary.

The core of the Super Bowl 50-winning Broncos was dominant, but it has almost completely evaporated. Following the departure of Chris Harris Jr. and Derek Wolfe in free agency, Von Miller remains the only starter on the defensive side of the ball. Offensively, the last remaining piece left in the middle of 2019 when Emmanuel Sanders was traded to San Francisco.

In the years after the championship, the 2016 draft class was impactful as six of the eight players started at least 45 games for the Broncos. First-round pick Paxton Lynch didn't pan out, but Adam Gotsis, Justin Simmons, Devontae Booker, Connor McGovern, Andy Janovich and Will Parks all made key contributions at times.

The 2017 draft class, though, seemed to stall that progress. Only three players from that class — Garett Bolles, DeMarcus Walker and Jake Butt — remained with the team entering the 2019 season, and Butt has played just three career games. Bolles, a steadily available player looking to curtail penalty issues, is the most successful player from the group. Second-round pick DeMarcus Walker, meanwhile, has made just one start.

Denver's fortunes seemed to change in the spring of 2018, and it appeared to coincide with a shift in strategy. After a draft in which the Broncos used picks on talented yet raw players like Bolles and cornerback Brendan Langley, Denver chose proven players in 2018.
