If you look at the Denver Broncos roster for their biggest weakness, I would likely choose the offensive line. Not due to their starters, but due to the lack of depth behind those starters. However, if you look at just the starting unit, then you might focus in on the defensive line group.
While talented there with their starters, there is concern over durability - especially with Randy Gregory. According to the latest defensive line rankings from Pro Football Focus, the Broncos defensive line is in dire straights heading into the 2023 season.
