Denver Broncos general manager John Elway has historically been great at signing free agents, and historically, he's done it without being among the league leaders in available cap space.
The Broncos have a ton of cap space in the 2020 offseason ($62 million projected) and obviously plenty of needs to be filled all over the roster. With roughly $10 million of that cap space set aside for your draft class and emergency funds later on, the Broncos could be going into February/March with around $52 in working cap space before making any roster cuts.
If the team makes some expected roster cuts, they could add almost $24 million to that figure, giving the team $76 million in cap space to work with.
