EDGE Analysis

Fitzpatrick started Thursday's preseason win over the Jaguars, completing 12 of 18 passes for 126 yards and a touchdown. The veteran signal-caller struggled to move the offense during the first half, but rallied to produce a touchdown drive in the third quarter capped by an 8-yard pass to Mark Walton. Josh Rosen then entered and compiled a 99-yard touchdown drive of his own, which featured a number of impressive scrambles and throws including a 39-yard connection to Isaiah Ford. Fitzpatrick has maintained a steady course for the Week 1 gig since minicamp, and may remain the favorite for the job, but it's not difficult to imagine a scenario in which Rosen lines up under center early in the regular season.
