Stat Analysis

With training camp approaching, Colin Kaepernick remains a free agent. We look at how more than just football reasons are driving this, and how Kaepernick would be an extreme rarity in NFL history if his age-30 season never actually happens.

Our look at defensive success against multiple-back formations has us scratching our heads about Miami. Are the Dolphins linebackers better than their reputation?

Are fullbacks disappearing from the NFL? Yes they are -- but in cities like Green Bay, they are not dead yet.

In which we ask the question: if you're not using 11 personnel, are you really playing modern football?

Denver's defense was still great at producing pass pressure, while two NFC East teams really improved over 2015. Also: pressure splits by number of rushers, and how sacks can be overrated. Just ask Brandon Graham (or Erik Walden).

A look at how passers did under pressure in 2016. Who extended the play the best: Aaron Rodgers or Russell Wilson? Is there any hope for Jared Goff after his rookie year? And does Ryan Tannehill consistently struggle with pressure more than his peers?

The absence of J.J. Watt allowed a very surprising name (and his equally surprising teammates) to make the most big defensive plays in the league last year.

By almost any measure, Matt Ryan was the NFL's best passers last year, but Dak Prescott was nearly as effective despite being paid about 2 percent as much. Guest columnist Kevin Kolbe looks at the best values among quarterbacks in the last five years.

Which players were truly best last year at gaining yards after the catch? Featuring surprising wide receivers and a dominant Gronk. Also: why does Bill O'Brien's Houston offense fail to produce YAC no matter which quarterback he starts?

Antonio Brown did not lead the NFL in receiving plus-minus for the third year in a row, so which wide receiver took his spot? Also: Dak to Dez, Gronk's unique season, the horrific Rams, and the running back with hands of stone.
