Well the scheme will fit better i think , it fits D Law better for sure in a 4-3 defense than what Nolan was running with a 3-4 defense , 4-3 is also most of the time better at stopping the run than a 3-4 at least through the gut anyways because of the fact that you have 2 DT in on 4-3 where as you have just 1 in 3-4 , and he runs a cover 3 on the back end which has 3 deep zones so that means that you're not gonna get a lot of deep throws unless it's blown coverage , plus this type of D i think will benefit D Wilson and Diggs as long as they can have zone discipline , because with zone you got more chances to pick off the football if it looks like you're on a man but back off of him and go to another man , this hire also i think gives me the idea that they are FOR SURE gonna draft either CB Surtain or Farley in the 1st round as these 2 could fit right into his system as you need real athletic players to play this type of defense
