I think people putting in the 2nd string rb at the true fullback posistion needs to be taken out of the game.
There should only be two players playing at the fb posistion in madden and that is a FB or a TE.
This doesn't go for shotgun sets, that is fine and normal and not really a true fullback posistion.
I think the rb sub for fb needs to be completely removed out of the game except on shotgun formations.
