Adrian Peterson is a former NFL MVP and an All-Pro running back who has led the league in rushing on three different occasions.

And according to NFL.com columnist Adam Schein, the likely future Hall of Famer is the most indispensable offensive player in the NFL.

Schein writes:

This is the fourth offseason in which I've made this list -- and **Peterson has topped* *the offensive group* *every single time*. Why? Well ...** *

*In his nine-year career, Peterson has logged 16 games in four separate seasons, all of which ended with the Vikings in the playoffs. *

In the five other campaigns? Zero playoff appearances for Minnesota. That, my friends, is indispensable. When Adrian Peterson plays a full season, the Vikings make the playoffs -- plain and simple.

After missing all but one game in 2014 … Peterson led the league in rushing last season (1,485 yards) and guided the Vikings to their first division title since 2009.

With Teddy Bridgewater still growing, Peterson is Minnesota's offense. And he racks up these numbers with the opposition designing the entire game plan around stopping him.

Peterson, the Vikings all-time leader rusher, has 11,675 career rushing yards and 97 career rushing touchdowns.

He was one of two running backs on Schein's list along with Todd Gurley of the Rams.

Rudolph focused on being well-rounded tight end

Some tight ends are known for their catching abilities while others stand out for their blocking prowess.

Vikings tight end Kyle Rudolph wants to be known for both.

Rudolph recently spoke with John Holler of Viking Update about working on his blocking to help make him a more versatile player.

Rudolph said he had a meeting with Vikings Head Coach Mike Zimmer during the bye week last season that opened his eyes.

*He didn't want to come off the field for Rhett Ellison or a fullback for pass protection and run blocking. He didn't want to be a two-down tight end who would come off the field in three- and four-receiver sets and perhaps at times when the team was grinding games out late. He wanted to be an every-down tight end, so his focus went more from being a receiving threat to paying more attention to his blocking assignments in both the run and pass game. *

"I just tried to make a concerted effort to contribute to help our team however I could," Rudolph said. "If that was going to be by run blocking, pass blocking, helping in pass protection and it wasn't going to be catching a bunch of balls, when he sat me down and told me that, I kind of viewed things differently."

*Rudolph feels that he is more well-rounded as a player because he embraced his blocking responsibilities and came to understand that, as the flow of a game plays out, his role could be drastically different – playing one game primarily in the backfield blocking and the next game stretching the seam of the defense. *

Rudolph had 49 catches for 495 yards and a team-high five touchdowns in 2015.
