@lo country I agree with all of your points. Currently battling it out on my status regarding our mutual take on the poor use of Gifford against an OT all day. He's not Jadeveon Clowney, so maybe don't use him as such.
Where are the mixed fronts? Bring 8 guys up to the LOS, rush 5/drop 3 or rush 3 /drop 5, etc. Make them at least think a blitz might come. This is a Diaco-level base 3-4 with poor in-game adjustments and it's maddening.
DB's need to learn how to turn their head and play the ball. If you're not even at least looking back toward the ball, you're gonna get flagged for any amount of contact.
