I think is the the crux of the issue, these guys function as a unit and are not statistically driven.. Seymour when healthy makes Warren better, both make Wilfork better on and on.. it is not that complicated, there are those who try to make it that way though.
It sounds like the way I 've read,and heard the Packers of the '60's played. They had a few plays, not complex but were so good at them it was basicaly "here it is stop us if you can"
