I’m not sure this is true. Their defense is hard to figure out. Their D is 27th in yards per play (Denver is 11th), 24th in red zone TD % (Denver is 7th), 18th in yards per game (Denver is 6th), 15th in points per game (Denver is 2nd), and 13th in points per play (Denver is 2nd). But they’re 2nd in 3rd down conversion % (Denver is 27th, go figure). A big one is that they’re 6th in turnover differential (Denver is 20th). So I think their D is fine, and is plenty good considering how damn good their offense is. But I don’t think it’s an elite defense by any stretch. Unfortunately, Denver’s offense isn’t even good against bad defenses so it may not matter much.
