Pretty sure Drew Lock and Teddy Bridgewater didn't help him.I think Fangio and Broncos losses had something to do with Mahomes, Hill and Kelce more so than who the Broncos had at qb. During that time the Chiefs were the top team in the league, I doubt we could say the Broncos would have been consistently better if they had a better qb.
He still had a top defense. That's the point.
