Is there a mechanism in play that "mandates" such defensive players such as Watt, Sue, Miller, Mack etc... be blocked by more than one player?
I believe this is that "special ingredient" that's missing with the player differentiation everyone is looking for during their gameplay experience.
Whether controlled by the AI or Hum player, these type of players don't force gamers to have to account for them
Even better is the AI having awareness to match its best DL/LB's against the weak areas of an OL and attack it to force the gamer to altar/change their gameplan.
Really making these type of guys special and hard to come by (unless you choose the team they're already on) would really add to all areas of the game.
