I think the key here is to use both schemes and mix it up a bit. Base can be 34 or 43, I don't care. However, we have personnel to run both with very little substitution. I think that we need to look at running a combination a bit more. The NFL is about creating miss matches. This is one way of doing that.
To be honest, it really surprises me that we haven't done more of this already. You look at our personnel and Canty is a natural LDE in a 43. Ferguson has been a better 1/2 technique DT then NT. Spears has played both LDE in a 34 and 3 Technique while at LSU. Ware can slide to RDE or play Rush LB on either side in a blitz situation. Singleton or Ayodele can play OLB. Ayodele or James can play MLB. Heck, you could probably even slide Roy down to play Will and bring in Glenn to play at FS. Davis plays a much better Strong then Free. I know it's not as easy has having a guy line up and play but most of these guys have good experience in a 43 scheme. Seems as if it would be a natural thing to do.
Who knows, maybe if we're lucky enough to get to the playoffs, we will end up doing this against one of those teams.
