The 43 is better against the pass... So if you believe that this league is going to more of a passing league then you should go to a 43...But its not easy finding great parts for a 43..Ask the falcons..They are struggling right now and they have run a 43 for a long time now. 34 or 43 the bottom line is you have to make plays...Bottom line.. Our secondary is in shambles right now so I dont think that it would matter much but I think we would get alot more consistent pressure especially against big personnel..Its not just the personnel in a 34 that make it hard to get pressure on a qb , its the gaps that they man thats the biggest problem with it IMO
it's not really harder it depends on what 4-3 you run. Mike Smith likes to have a defense that relies heavily on the defensive line getting pressure and sending very little, if any, blitzes. The problem has been that outside of Abraham, they don't have that.
