You have Tony Pollard. Give me Achane in the 3rd and Deuce Vaughn in the 6th, and Luepke in the 7th and I will be very happy.
TP with Luepke as the blocking back. Achane and Vaughn might get injured due to size, but if they don't, they have special qualities (they aren't every down backs, but are weapons).
Dallas needs weapons in the return game, in the screen game, at slot, on sweeps.
String together enough weapons and you have a chance to score on every play, and can adjust to the defenses weakness.
