The reason we are so terrible is simple:
We have terrible, terrible, WRETCHED QB play...and terrible coaching.
Good schemes make average players look great (sometimes). We have shit, shit, SHITTY schemes...Romeo is so soft and plays such a shitty defense it's disgusting. We show ZERO aggression. Bend don't break doesn't cut it in the passing NFL.
Would you rather put a ton of heat on the QB and risk an 80 yard quick TD here and there...or just let teams consistently pick up 3rd and 6 all game long because you're soft as shit and instead of an occasional quick hitter they go on 5 long scoring drives that kill the defense in the process?
We are a competent staff and QB away from being a good football team.
I've been very complimentary of Denver all season long and think they have AN ELITE DEFENSE with AN ELITE SCHEME...but I do not think they have more than 1 win worth of talent than us if you take Manning out of the equation (see 2011)...and outside of the WR position I don't see them overwhelming us on any other unit.
