Stidham entered his true freshman year at Baylor in 2015 as the backup to Seth Russell. He appeared in the first seven games, completing 24 of 28 passes for 331 yards and six touchdowns. After Russell suffered a season-ending neck injury during Baylor's seventh game, Stidham took over as the starter. He started his first career game against Kansas State. He finished the game completing 23 of 33 passes for 419 yards, three passing touchdowns and a rushing touchdown. In his second career start against Oklahoma, Stidham injured his back in the first quarter, but he was able to remain in the game. He finished the game completing 16 of 27 for 257 yards, two touchdowns and two interceptions in the 44–34 loss. The following week, despite being questionable to play leading up to the game, Stidham made his third career start against Oklahoma State. He injured his hand and ankle in the first half of the game and did not return to the field for the second half. On November 25, 2015, Baylor head coachArt Briles announced that Stidham's ankle injury was a chipped bone in the back of his ankle and Stidham would be sidelined for the remainder of the regular season. It was reported that Stidham might be able to return for Baylor's bowl game, but on December 19, Briles announced Stidham would miss the 2015 Russell Athletic Bowl. In the wake of a sexual abuse scandal at the school and the firing of much of the coaching staff, and dissatisfaction backing up quarterback Seth Russell, on July 7, 2016, Stidham announced he would be transferring from Baylor.
