I really don't think you can two-gap all that consistently. Your idea seems like a good one, but what about the 4 techniques? They're being controlled by the cpu, so you don't really get a true 2 gap style. Besides, I think Casey was really talking about how defensive alignments affect blocking assignments, which is really where the differences b/w two-gap and 1-gap styles come into play. Look at how these two fronts affect the blocking of a strong side wide zone play:
...............................................T.. ........................
.................................................. ....F.................
...............................................Q.. .......................
...............................TE...T...G...C...G. ..T...............
...............................R.........3....0... ......5..............
.....................................40..........2 0I.....50...........
...............................................T.. ........................
.................................................. ....F.................
...............................................Q.. .......................
...............................TE...T...G...C...G. ..T...............
...............................R.........3......1. ......5..............
.....................................40......10... ...40I...........
In the 1st example, the nose is going to be combo blocked by the center and backside guard, while in the second example, the combination is going to happen on the 3 technique, leaving the guard to cut-off the nose. This minor adjustment in alignment (major difference in philosophy) has vastly altered the combination schemes by the offensive line.
In addition, I think it would be a good idea to categorize players as what kind of style they are best at in their ratings (1-gap penetrator, gap control, 2 gapper)
