In the second part of his look at scrambling quarterbacks, guest columnist Keegan Abdoo shows how Lamar Jackson and similar mobile quarterbacks can limit the playbooks of opposing defensive coordinators.

What kind of impact does a running quarterback like Lamar Jackson have, and how does that change between NCAA and NFL football? Guest columnist Keegan Abdoo starts to answer those questions by looking at what coverage schemes are most vulnerable to scrambles in college and the pros.

On which route did Jalen Ramsey make quarterbacks look trashiest? How good were the Super Bowl champion Eagles? Also: major déjà vu for New England, and a look at the trade-off between touchdowns and interceptions for each route.

Why isn't there more route variation for Aaron Rodgers in Green Bay? Was Eli Manning still washed up on the most common routes in 2017? And we offer solutions for Jameis Winston's vertical woes and the right kind of fade for Derek Carr.

Our intro to DVOA by routes focuses on receivers. Which wideout was the best at the game's two most common routes? Also: an argument in favor of the fade, how the Dolphins should replace Jarvis Landry's screens, and T.Y. Hilton's wacky 2017.

A question from a reader has us diving into week-by-week DVOA splits, looking at how both run and pass defense change over the course of the year. Is wear and tear to blame for defensive declines, or does Old Man Winter have something to say?

The Jaguars went from last to first in DVOA on wide targets after adding A.J. Bouye. How will other teams fare in 2018 after the movements of Richard Sherman, Patrick Robinson, and Tyrann Mathieu?

Our 2019 Pro Football Hall of Fame predictions find three first-ballot locks. Is Tony Gonzalez the greatest tight end of all time? Also: Ed Reed's brilliance, a crazy trade for a running back, and what do we do about London Fletcher and Asante Samuel?

Can Saquon Barkley diversify the New York offense? Is Le'Veon Bell really that unique of an offensive weapon? Just how great was Rob Gronkowski again, and how badly did Dallas misuse Jason Witten?

Part II of our look at slot vs. wide focuses on quarterbacks. Who did most of his work throwing to the boundaries, and who was more prone to work the middle of the field? Includes obligatory mentions of Deshaun Watson, Jared Goff, and Jimmy Garoppolo.
