...Pretty much what WPR is saying.
This is just a pure opinion filled with a ton of speculation, coupled with a continued awareness that this is pre-season and possibly "vanilla-ized" in many respects.
I don't like the "fit" of the GBP and zone coverage. I predict this to be my personal arena of greatest concern and projected bitching. Our very vanilla 4-3 with man-press coverage at least allowed me to say (under my breath to myself, mostly) well, at least the WR 'made a play', or...'he was well-covered' , or some-such.
I fear that this year I will be screaming at my TV about failed coverages, etc.
This on a team that brought zero heat last year. YA YA YA I know, total different animal heat-wise with the 3-4....but when that heat is not there...OUCH, it's gonna hurt. That is my fear, and I readily admit a large chunk of it is semi-unfounded due to what has come before. 6-10 football teams with a complete shit D in the previous year will have paranoid fans such as myself.
I am loving the 3-4 when it works as planned, btw. What a thrill.
