To me since ive played in a rules Two Thousand ruleset no stacking, and now learning the 4.0 way of play paracticing with and without stacking, now im not gonna EF/MF technical and go that route, to me a simple word, Adapt. ive noticed on a solitaire level against the stack, its a simple matter of adapting to the stack weather it be Left Right Center, see the problem is on O with some coaches instead of just doing there thing they counter to what the D has done with the Stack , now yes its a move, but lets say your O line can blast away from that stack and cause movement away from the pressure, alot things can be done to counter with proper base Strategy, Now George Diamond Brought a simple direct and truthful point, bigger boards would spread out the D and O so that is a very good point. To me It doesnt matter under the 4.0 set Stacking or No Stacking man this is so minor! Strap Up your Pads lets just play jeesh.
