Who Is Brady Cook? A Look at the Jets Quarterback’s Journey to Becoming a Starter in NFL

The New York Jets enter Sunday with uncertainty, urgency and a new quarterback stepping into the spotlight. What began as a depth decision has quickly evolved into a defining moment for a rookie who was not expected to lead the huddle this season.

How Brady Cook arrived at this point, and what it means for a struggling Jets offense, creates a storyline worth following.

Brady Cook’s Path From Missouri Leader to Jets Starter

Jets head coach Aaron Glenn announced Friday that rookie Brady Cook will start against Jacksonville after injuries sidelined Tyrod Taylor and Justin Fields. Glenn confirmed, “Brady will be out starting quarterback this week.” Adrian Martinez, who re-signed to the practice squad earlier this week, will serve as the backup.

Cook took over last Sunday after Taylor exited against Miami, entering the game down 21–0 and finishing 14 of 30 for 163 yards with two interceptions. Glenn defended the performance, emphasizing Cook’s lack of prep time and pointing instead to his readiness now. He said, “I have all the confidence in the world…he’ll be a good player in this league.”

The rookie becomes the Jets’ first undrafted free agent quarterback to start since 1973. His college career at Missouri showcased consistency and leadership across 46 games, with 9,103 passing yards, 49 touchdowns, and only 15 interceptions. He added 1,209 rushing yards and 20 rushing touchdowns, totaling 10,222 yards of offense, and started four bowl games while earning MVP honors in three.

Glenn praised Cook’s influence beyond the numbers, highlighting his work ethic, communication, and command of the offense. He noted, “All those things shows that he’s been studying his butt off for this moment.” That preparation now meets opportunity on a team that has cycled through quarterbacks at a rapid rate. Cook becomes the tenth Jets starter since 2022.

Context makes Cook’s challenge even steeper. According to PFSN’s Offense Impact metric, the league-wide average Offense Impact Score is 74.4, a mark well above the Jets’ production. The Jets hold a 3–10 record with an Offense Impact Score of 62.0, ranking 29th in the NFL.

PFSN assigns the unit a D-minus grade, and the Jets sit 798th in overall rank among team-season evaluations. These metrics highlight the limitations of the offense and underscore why quarterback instability has significantly contributed to the decline.

Glenn framed Cook’s start as a pivotal opening rather than an emergency measure, telling him, “Sometimes you only have one shot and when you have that one shot, you have to shine in that shot.” For Cook, that shot arrives Sunday. Whether he can elevate an offense operating far below league averages will shape both his future and the Jets’ trajectory in the weeks ahead.
