The Denver Broncos were aggressive in free agency last year, signing guys like Evan Engram, Dre Greenlaw, and Talanoa Hufanga. The returns on those players have largely been solid, and with money to spend, Russell Wilson's contract off the books, and Bo Nix on his rookie deal, Denver has no reason to not be aggressive once again.
The NFL free agency classes are always typically filled with good players, and teams have to be careful during this time to not overpay for players, as that is usually what hurts the teams in the long-term. Well, the Broncos could make a few major deals to shore up remaining holes on their roster.
