1. Denver Broncos
I would take Joey Bosa over either of the starting edge rushers that the Denver Broncos have but as a duo, Denver is better than LA. The Broncos have two legitimate Pro Bowlers, the Chargers don't have another great edge option.
Denver has the tandem of Bradley Chubb and Von Miller, who are in opposite ends of their careers. Chubb is a young edge rusher who is entering the prime years of his career while Miller is undoubtedly a future Hall of Famer who is exiting his prime.
The signs of regression are there for Miller, especially considering that he did not play at all in the 2020 season. However, he has the pedigree and the ability to get the benefit of the doubt and the worst-case scenario for him is being above average.
Any regression that Miller sees should be matched by improved play from Chubb. Chubb has already established himself as one of the best edge rushers in the league and he is only going to get better.
It would take more regression than expected for Miller as well as a massive breakout season (likely from Nwosu) for the LA Chargers to surpass the Broncos when it comes to the overall edge-rushing position.
