Mason needs Vikings offense improvement; goal-line role offers upside if environment changes.

Mason is ranked 41st among running backs and is not a pass catcher or pass pro player; he doesn't play on third down. His efficiency rushing is slightly lower than the prior year but still more efficient than Aaron Jones. He is a passenger in fantasy and needs a good environment to become a fantasy starter, but if the Vikings offense turns around, Mason is the one most likely to benefit given his goal-line role and ability to handle big workloads.
