[1] He attended the College of San Mateo in his freshman year, playing in 11 games, and completed 104 of 194 passes for 1,870 yards and 21 touchdowns.

He threw for 2,785 yards and 18 touchdowns that season on a struggling Rainbow Warriors team that lost nine of the last ten games, mostly attributed to a battered offensive line whose position coach left mid-way through the season, and top receiver John Ursua lost to a torn anterior cruciate ligament.

[9] At Oklahoma State, Brown joined a crowded QB room competing for the Cowboys starting quarterback job following the departure of the four-year starter Mason Rudolph.

Following Cornelius' graduation and departure, Brown was one of the favorites to win the starting quarterback job, competing for it with redshirt freshman Spencer Sanders.

[14] He started his first career game as a Cowboy against the West Virginia Mountaineers the following week, where he racked up 196 yards and two touchdowns in a 20–13 victory.

He entered the game after starting quarterback Zach Collaros was pulled from play by injury spotters after he took a hit to the head.

[21] As a pending free agent, Brown's playing rights were traded to the Ottawa Redblacks on January 18, 2024, in exchange for a fifth-round pick in the 2024 CFL Draft.
