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
