Diving right into the running back room and their unquestionable star Dalvin Cook – how could we not be excited for the potential once again.  Cook managed his best year on record which lifted him to compete for the prize of being one of the leagues best runners.  However, durability continues to be a concern as he lost two more games to injury and concluded the year playing at far less than 100-percent.  The Vikings clearly realized they need supportive pieces in this room and that came from their rookie Alexander Mattison and Mike Boone for relief.  Mattison showed a good level of skill and should remain as the change of pace back in this offense.  No matter how we cut it, this offense will again go through Cook and we sure hope his body can hold up.
