3-4 vs. 4-3

[Defensewins]

With a lot of winning teams (Ravens, Rams, 49ers etc) running variations of the outside zone running game and using the play action boot leg off of that. I thought it was interesting to learn how it was successfully defended by the 49ers and Patriots. Most importantly the chess game of adjustments that Gruden and staff did not have the brain capacity to do, but our new defensive staff does. Please note the 49ers run the 4-3 as base with D-line playing 2 gap and secondary playing a zone 4 deep quarters coverage. We will be playing 4-3 as our base now, which our D-line is our strength so it makes sense. Plus i have always preferred the 4-3 as base D.
