3. Denver Broncos
The Denver Broncos do not have a great offensive line group, either. However, there are some things in the Broncos' favor that put them over the Raiders. While some may perceive a huge gap between the two teams, I would not be shocked whatsoever if Vegas has a better O-line than Denver.
The main reason why the Broncos get the nod over the Raiders is their left tackle, Garett Bolles. Bolles blossomed into one of the best tackles in the entire NFL last season and is better than any offensive lineman that the Raiders have.
Even if they are just as weak (or weaker) in other areas, having an elite, All-Pro-worthy left tackle gives you the advantage.
That is not enough to rank them any higher than third, though. The Broncos are relying on Bobby Massie to play right tackle when Massie is 32 and his ceiling in the league has been average. Dalton Risner is a former second-round pick who is entering year three and has been average while Graham Glasnow is in the same average boat without the potential of breaking out.
The center position, like the rest of the offensive line outside of left tackle, is mediocre. Lloyd Cushenberry certainly is serviceable but he is not a center that you get all that excited about.
The one part of the Broncos' offensive line that I envy as a Charger fan is Quinn Meinerz. Meinerz fell in the draft, likely because he is coming from a small school, despite showing all of the right signs in the Senior Bowl that he will be a quality interior lineman.
If Miller, Incognito and Leatherwood all hit their absolute peaks then Vegas could be better. If not, it is Denver.
