Mason is still out there on 59% of waiver wires, and he's certainly worth an add given his recent usage. He has at least 14 carries in four of his last five games, and hit the 29-tote mark this past week against Denver. The main reason he hasn't been a complete fantasy stud is because the Rams offense is a little inept and he's only found the end zone once over this time. If he's out on the wire, he's a must add at a position that's always lacking start-worthy players.
