Mobility matters at the quarterback position more than ever in the NFL. Tom Brady is a glaring and all-time-great exception, but look at the majority of the league's top quarterbacks: Aaron Rodgers, Russell Wilson, Carson Wentz, Cam Newton, Ben Roethlisberger and Andrew Luck (when healthy) all are often dominant with their legs. Matt Ryan and Matthew Stafford can move. Drew Brees can dance. Deshaun Watson is electric. The NFC East is full of QBs who do damage with their feet: Wentz, the Cowboys' Dak Prescott, and both Washington's outgoing (Kirk Cousins) and incoming (Alex Smith) starters. Nick Foles, the Eagles' Super Bowl MVP, isn't a tuck-and-run player, but his elusiveness in the pocket is a major reason Philly won it all, including on what I felt was the play of the game: Foles danced away from pressure and threw on-target, off-balance, to tight end Zach Ertz for a two-yard gain on 4th-and-1 from the Eagles' own 45-yard line with under five minutes left and New England up, 33-32. The Patriots had scored touchdowns on three straight drives to start the second half. But the Eagles converted that fourth down because of Foles' feet, and Foles hit Ertz for the go-ahead touchdown later that drive. And then Brandon Graham forced a Brady fumble, and one Jake Elliott field goal and a failed Patriots Hail Mary later, the Eagles were world champs. And then there's Eli Manning and the Giants, and the interesting question of how new head coach Pat Shurmur and offensive coordinator/quarterbacks coach Mike Shula will build a thriving offense around Manning, 37, one of the least mobile quarterbacks in an increasingly athletic league at the most important position in the sport.
