we are not talking the same things. I definitely do not advocate removing your top players from the field. MM's packages are bull sh--.
However, the 11 players that take the field on any given play should be available to perform their responsibilities. That is what makes a dangerous offense - having 5 skill players that can do anything asked of them at any time AND have a RT that will catch a TD to boot... Teams that are effective in the red zone don't have one RB and one WR that get the ball because "this time it is important". It's predictable and defendable.
