I keep reading about "system" guys and they all seem to come from the successful teams in the NFL. My question is this:

If players from "systems" (Indy, Tampa, NE, etc...) are so successful in their team's system and almost immediately become mediocre when they go to other teams, is the Saints' "system" the wrong "system" for success? Should our defensive system change (from man to man) in order for the defense to be more successful??
