On Wednesday, Pro Football Reference released their Initial Approximate Values (AV) for the 2017 season. Players featured in the top 100 on this list generally had both a healthy season and a highly productive season.

For those not familiar with Approximate Value, Pro Football Reference founder Doug Drinen created it as a way of quantifying the value of an NFL player’s contributions on a universal scale that can be applied across positions and years.

As described by Drinen himself, “Essentially, AV is a substitute for — and a significant improvement upon, in my opinion — metrics like ‘number of seasons as a starter’ or ‘number of times making the pro bowl’ or the like. You should think of it as being essentially like those two metrics, but with interpolation in between.”

To help show a baseline value for AV, of the 213 NFL players who started all 16 games in 2017, 8.6 was the average AV. The highest recorded AV season since the 1970 NFL-AFL merger is 26. This came during LaDainian Tomlinson’s legendary 2006 season, in which he was responsible for 2,323 yards from scrimmage and 31 touchdowns.

The list of the top 100 players this season featured the following five Eagles players:

No. 19: Jason Kelce – Center – 15 AV

Despite not making it to the Pro Bowl, Kelce was acknowledged by another prominent NFL analytics site for having an elite year.

No. 28: Fletcher Cox – Defensive Tackle – 14 AV

No. 31: Lane Johnson – Right Tackle – 14 AV

No. 41: Carson Wentz – Quarterback – 14 AV

That Wentz made this list after he missed three-and-a-half games is especially telling of how great of a year he was having.

78: Brandon Brooks – Right Guard – 10 AV

It is somewhat surprising to see Brandon Graham left off of this list, but Cox, Johnson and Brooks all certainly played very well and deserved to make the cut.

Other observations from the list:

The Dallas Cowboys had four representatives: DeMarcus Lawrence (34 out of 100), Zack Martin (48), Dak Prescott (49) and Travis Frederick (65). The Washington Redskins had two representatives: Kirk Cousins (53) and Ruan Kerrigan (69). The New York Giants were one of six teams not represented in the top 100. The top five most represented teams were the Minnesota Vikings (9 players), the Jacksonville Jaguars (7 players), the New England Patriots (7 players), the New Orleans Saints (7 players) and the Kansas City Chiefs (7 players). Tom Brady of the New England Patriots and Todd Gurley of the Los Angeles Rams were the highest-rated players in 2017, each with an Approximate Value of 19.
