Consistency is the greatest asset to players in the NFL.
Players who can continually perform at a high level excel beyond expectations and establish themselves as one of the best at their respective positions in the league.
The following group of NFL stars have been playing at an extremely high level for years and are continually relied upon by their teams.
Drew Brees is the essence of consistency.
The Saints quarterback is a team leader who continually performs at an unbelievable level. The 32-year-old has thrown 33 touchdown passes, 4350 yards and had a 65.0 completion percentage in each of the last four seasons.
The Purdue product has led New Orleans to three straight playoff appearances, including a Super Bowl title in 2009.
Brees is also extremely consistent on a week-to-week basis. The perennial Pro Bowler has thrown a touchdown pass in 41 straight games, an unbelievable stat that ranks second in NFL history.
All Day is terrific every day.
The Vikings running back is one of the most consistent backfield threats in the league today. He has missed just five games in five seasons as a pro and has amassed over 230 carries, 1250 yards and 10 touchdowns in each of those seasons.
The Oklahoma product has never not been selected to the Pro Bowl roster, and he has led the Vikings to a NFC Championship berth in 2009.
The former first-round pick is constantly relied upon by Minnesota to perform at a high level, and he never seems to disappoint.

Larry Fitzgerald is an absolute beast.
The Cardinals wide receiver is the only reliable weapon in Arizona's dismal offense, and he continues to produce terrific numbers.

Even with horrendous quarterback play, Fitzgerald continues to establish himself as one of the most dangerous offensive threats in the NFL.
Honorable Mentions: Greg Jennings, Marques Colston, Roddy White
Jason Witten changed how tight ends are involved in NFL offenses.
The Cowboys star was one of the first at his position to be a consistent ball-catching threat, and he has continued to perform at a high level for years.
The Tennessee product has eight straight seasons of at least 60 receptions, 750 yards and a touchdown. He has appeared in the Pro Bowl in each of those eight seasons, a record streak for a tight end. The 29-year-old has missed only one game in his entire nine year career.
Witten has shown that a changing quarterback has no effect on his play, and he can be a consistent and reliable weapon in any offense.
Honorable Mentions: Tony Gonzalez
Jake Long is the best tackle in football, mainly due to his unbelievable consistency.
The former No. 1 overall pick continues to lead the Dolphins offensive line and provide his quarterback with plenty of time in the pocket. He also opens up holes for running backs to sneak through and explode into the opponent's secondary.
Long missed the first game of his professional career this Sunday, and the Michigan product has made the Pro Bowl in each of his first three seasons.
Honorable Mentions: Jahri Evans, D'Brickashaw Ferguson, Joe Thomas
Carl Nicks is one of the unquestioned leaders of arguably the best offensive line in football.

No center means as much to their respective team as Nick Mangold.

Mangold is the most reliable center in the game today in a landslide.

The mammoth nose tackle has missed just a few games in his entire career, and he has appeared in three Pro Bowls over the last four seasons.

The Vikings star has recorded at least 11 sacks in five straight seasons, and he has appeared in three Pro Bowls in that time period.
The 29-year-old is arguably the most consistent pass-rusher in the league today, and he can be relied on to constantly pressure the opposing quarterback.

The Cowboys' elite linebacker has recorded an amazing 96 sacks in just seven seasons, and has amassed at least 11 sacks in each of his past six seasons.

Darrelle Revis may be the greatest cover corner the league has ever seen (except for Deion Sanders).
The Pittsburgh graduate is consistently relied upon to shut down the opponent's No. 1 wide receiver, and he has been extremely successful in doing this. Revis has shut down so many star wideouts that he is nicknamed "Revis Island."
The former first-round pick is barely targeted by opposing quarterbacks, as they are too afraid to throw it his way.
The Jets star has appeared in three consecutive Pro Bowls and is the main reason why New York's pass defense is so stingy.
