NFL Positional Value Chart

1. Quarterback

If you have a bad quarterback, one who throws a lot of interceptions, you most likely are not going to make the playoffs. If you have a decent game manager, you can win but you need a hell of a support cast. A good quarterback, not only creates more yards than any other position on the field, but also opens up lanes for running backs, makes his receivers look better, and keeps his defense off of the field and rested, making them better. In fact, 18 of the 19 last Super Bowl winning quarterbacks made a Pro Bowl before winning the Super Bowl. Eli Manning is the only one to not make the Pro Bowl before winning the Super Bowl and he eventually made it the next year. There’s a reason for that.
Best in the league: Peyton Manning, Drew Brees, Aaron Rodgers

2. Offensive Tackle

A franchise quarterback isn’t much good if he’s on the ground every play. Not only do sacks and hits disrupt a quarterbacks rhythm, but too many over a long period of time can cause a young quarterback to develop David Carr syndrome and a veteran quarterback to develop Marc Bulger syndrome. Offensive Tackle also support the running game as well.
Best in the league: Joe Thomas, Jake Long, Jared Gaither

3. Defensive End/ Rush Linebacker

Well if hits can do things that bad to quarterbacks, it only makes sense that the guys who hit them are of great importance. It is an old and time tested football saying that in order to win you need a quarterback, to protect your quarterback, and to get to the other teams quarterback. Defensive ends are not the only players who accumulate sacks and hits and pressures, but they are the only ones whose first priority is getting to the quarterback. Rush Linebackers are essentially the same, only they line up at different spots on the field in different schemes and more often have to drop back into coverage. Nonetheless, rush linebackers normally lead their team in sacks, pressures, and hits.
Best in the league: Jared Allen, DeMarcus Ware, Dwight Freeney

4. Running Back

Well if you don’t have a franchise quarterback is the next best thing in terms of gaining yards. Franchise running backs don’t win you Super Bowls like quarterback do, but they certainly help. They can tire out the opponents defense and open up passing lanes for the quarterbacks and also catch passes and even do some blocking.
Best in the league: Chris Johnson, Ray Rice, Adrian Peterson

5. Wide Receiver

Quarterbacks can win without great wide receivers, in fact some can even argue that quarterbacks make great wide receivers, but it certainly will help any quarterback to have a speedy deep threat and a reliable possession guy at his disposal to help him guide his team. Just ask Eli Manning how he likes playing without Plaxico Burress (10-11 including playoffs since Plax shot himself in the leg).
Best in the league: Andre Johnson, Reggie Wayne, Vincent Jackson

6. Cornerback

That being said, if you have a great #1 cornerback, he will nullify the opposing #1 wide receiver. Darrelle Revis shutdown every #1 wide receiver he faced last year. Don’t think that didn’t win them some games. If your quarterback is forced to essentially play 10 on 10 without his best receiver, he’s going to struggle.
Best in the league: Darrelle Revis, Charles Woodson, Leon Hall

7. Nose Tackle (3-4 only)

Other than rush linebacker, no front 7 position is more important to a 3-4 than nose tackle, even more than a defensive tackle to a 4-3. They don’t put up huge stats, but having a huge shield of a nose tackle than can occupy two blockers and also move around some makes everyone on the defense better.
Best in the league: Vince Wilfork, Kelly Gregg, Shaun Rogers

8. Defensive Tackle/3-4 Defensive End

Essentially the same position, only a 3-4 end lines up a little farther outside, but the job description is the same. Be a big body against the run and also get to the quarterback if you can.
Best in the league: Albert Haynesworth, Kevin Williams, Haloti Ngata

9. Middle Linebacker

Slightly more important in the 3-4, but they are the heart and soul of a defense and while they aren’t the most important, they are usually they most outspoken and the most versatile defenders on the field.
Best in the league: Patrick Willis, Ray Lewis, Brian Urlacher

10. Offensive Guard

Just two offensive tackles alone isn’t going to be enough to protect your quarterback, though guards are primarily designed to get the big defensive lineman away from your running back and are not as used against the pass rush because of their size and position on the field, and for that reason they are ranked lower than offensive tackles.
Best in the league: Jahri Evans, Steve Neal, Chris Snee

11. Outside Linebacker (4-3 only)

Not quite as much of a versatile defensive player as a middle linebacker, and you can get away without great outside linebackers as shown by the fact that neither the Saints nor the Colts have good outside linebackers this year. Their main job is cleaning up the messes of the defensive line and chasing down running backs out of the backfield. They can also be blitzed.
Best in the league: Daryl Smith, Brian Cushing, Lance Briggs

12. Tight End

They may be more important to rookie quarterbacks than veterans, but most quarterbacks enjoying having a good safety value tight end who can catch the ball over the middle. Their job description includes both catching the ball like a receiver and blocking like a lineman, but because of their hybrid type status, they aren’t extremely important.
Best in the league: Jason Witten, Antonio Gates, Tony Gonzalez

13. Center

The most underrated position on the field, there’s a reason that Peyton Manning does so well, he has had the same center snapping him the ball for his entire career. That definitely helps. They are also the smartest offensive linemen in terms of football knowledge, oh, and they also have to do some blocking. Just look at what happened to the Eagles after Jamaal Jackson got hurt for the first time in many seasons, Donovan McNabb looked uncomfortable and the entire offensive line fell apart.
Best in the league: Jamaal Jackson, Jeff Saturday, Nick Mangold

14. Safety

They aren’t necessary to a good team, but they certainly help. The Steelers have given up 10 more points per game over the last 2 years in games in which safety Troy Polamalu missed than in games he played in.
Best in the league: Troy Polamalu, Ed Reed, Nick Collins

15. Kick Returner

Nothing energizes a team more than a kick return touchdown, and they also give you good field position, the only issues, the difference between good ones and bad ones in terms of yards per return is minimal and even a good one will only score like once or twice a year. Their career length also isn’t very long.
Best in the league: Joshua Cribbs, Clifton Smith, Johnny Knox

16. Punt Returner

Basically the same as a kick returner, but because of the situation, they often get a much smaller chunk of yards per return. 10 yards is good. Their career doesn’t last long either.
Best in the league: DeSean Jackson, Joshua Cribbs, Quan Cosby

17. Full Back

Not all offenses even use one, but having a big fullback that can run and catch the ball, in addition to block, adds an extra little element to your offense.
Best in the league: Leonard Weaver, Le’Ron McClain, Ovie Mughelli

18. Punter

A good punter can make a good defense even better by setting them up with good field position, the only issue, they are only used when struggling so if you’re a good team, they aren’t extremely necessary.
Best in the league: Shane Lechler, Andy Lee, Ben Graham

19. Kicker

They can kill you or not kill you, the issue, one who doesn’t kill you one game, can kill you the next. They are extremely inconsistent.
Best in the league: Matt Prater, Sebastian Janikowski, Stephen Gostkowski

20. Special Teams

There’s a reason all the special teamers are the backups of other position that you can risk getting hurt. Much love for the position, it takes a lot to suck up your pride and play special teams, but they aren’t super important. You can only really tell when they are bad and miss a tackle. The holder and the long snapper are a little bit more important, but not much.
Best in the league: Tim Shaw, HB Blades, John Wendling
