I would also add that there’s a complimentary football component within the 3 phases.
On offense, if you can’t pass, it’s harder to run because the defense can stack the box. If you can’t run, it’s harder to pass because the defense anticipates and loads up on the pass.
On defense, what good is a stout run defense if you can’t cover (Eagles last year)? What good is an excellent secondary and pass rush, if you can’t stop the run (Dallas last year)?
On special teams, how much does a great punter who flips the field help you if your kicker can’t make field goals.
Drilling down, what good is an elite QB if your receivers stink or your OL can’t protect? What good is having an elite RB if the OL can’t open holes or an elite receiver if the OL can’t provide time or the QB can’t deliver the ball?
You are 100% correct on CF, and it relates to every facet and even every play the coordinator calls on offense or defense.
Football is the ultimate team sport. You cannot defeat the best teams, especially in the playoffs, when your offense and defense are one dimensional because a one dimensional defense will not hold up when you need them, and a one dimensional offense will not deliver consistently vs good teams. Last year we had no run game or run defense. That put a ton of pressure on both the offense and defense vs top, more balanced teams.
I think we finally took steps in the draft to fix this with multiple OL picks and defensive selections targeting the run defense, but we are likely still a year away from real complementary football.
