Coverage for Empty sets within the 4-3

Coach with the 4-3 scheme and the empty set the question here is do you want to defende the box with 5 or 6 defenders first with 5 in the Box- to the 2 receiver side walk the weak LBer out to the 3 receiver side put the SS on number 2 and the Sam backer on number 3 inside with the Mike LBer in the middle of the box. I would perfer going to a 3 man front with 2 inside Lbers with 4 over 3 and 3 over 2 on the 2 receiver side. Coach CAmpbell
