Agree with a lot of this though my point about saving bullets was speaking more to the idea of Dline stunts, using a spy or stacking the box vs. certain teams, creative blitz packages, etc. I like your All-DE rush concept if we could ever generate a 3rd and long.
McD would try this stuff in the RS in prior years, and it would lead to wins. Now it feels like he's banking on the talent to win games, and we just don't have much of that on the defensive side of the ball anymore.
My theory is McD wants everything to look the same pre-snap. Give them as few different looks as possible, and save the best stuff for the playoffs. The problem is you still have all that tape from prior years, and you may wind up having to use your best stuff on the road because you lost winnable games trying not to show your cards.
I've often heard coaches talk about not using your best stuff out of the gate because if it doesn't work you're screwed - you've already made your adjustment. But there's something to be said about not letting them get a rhythm to begin with. You know Stafford excels vs. zone. You know Lamar/Henry present added challenges in the run game. You know healthy Kyler can beat you with his legs once he gets out of the pocket. You know Tua makes quick decisions if you give him space. Why let these people do what they do best and gain confidence before making any adjustments? You're just playing with fire, needlessly.
I'll happily eat my words if McD's theoretical plan works in the postseason, but I'm not holding my beath.
