Alexander Mattison ticketed for every-down role?

ESPN's Kevin Seifert writes that "all evidence suggests" that the Vikings will use RB Alexander Mattison "in the same every-down role that [Dalvin] Cook performed last season in coach Kevin O'Connell's offense." Cook played 72% of Minnesota's offensive snaps last year, averaging 15.5 carries and 3.3 targets per game. He ranked 12th among RBs in expected PPR points per game and 14th in actual PPR points per game. Mattison will return a nice profit for fantasy teams if he approximates that role. Seifert also believes that RB Ty Chandler is the favorite for the #2 job, ahead of RBs Kene Nwangwu and DeWayne McBride.
