Blitzing a minimum of 6 on every play against 4/5 receiver sets that are expecting it. Having D.B.'s whose reads somehow put them 3-4 yards behind receivers running Go Routes with about 100% consistency.
Worse, calling the occasional base set of sending strictly the 3 or 4 down linemen and leaving 7/8 in coverage, seeing that call be successful, and then immediately rushing 7 the next several plays.
I despise him for his stupidity.
