Dalvin Cook is entering his third NFL season. He still has not played the equivalent of one NFL season, his career ledger at 15 games.
As the Vikings initiate an offensive makeover in scheme and coaching staff, quarterback Kirk Cousins, by nature of his position, remains the most important player to the success of the operation.
Cook is No. 2 on that list.
The running back is a difference-maker with special skills — speed, instincts, vision — that make the offense significantly more difficult to defend when he's on the field and the ball is in his hands.
And "on the field" should be in bold capital letters.
The Vikings desperately need Cook to stay healthy. He's been unlucky in that regard. His position can be unforgiving on the body. But the Vikings have a mandate to run the ball better this season. Their entire scheme — and coach Mike Zimmer's mood — revolves around that.
"Leaders on the team come and talk to me," Cook said Monday. "It's now or never. That's how you look at it every year — now or never. I set myself up in the offseason and summer to get myself in position to do some big things this year. I know these guys are leaning on me. I worked extremely hard to get here."
The vibe around the team is one of optimism as it relates to Cook, now that he's healthy after separate injuries ruined his rookie year (torn ACL in Week 4) and severely affected his 2018 season (missed five games because of a hamstring injury).
