He played college football for the USC Trojans, Georgia Bulldogs (where he won the CFP national championship as a backup to Stetson Bennett), West Virginia Mountaineers and Rice Owls.

Within three weeks, Daniels was named the starter over incumbents Matt Fink and Jack Sears,[12] making him the second true freshman in school history to start a season opener.

[14] During the season opener against the Fresno State Bulldogs, he tore his ACL during a sack in the second quarter; at the time of the injury, he had completed 25 of 34 passes for 215 yards, a touchdown, and an interception.

[15][16] Following the emergence of Slovis, USC head coach Clay Helton announced that Daniels entered his name in the NCAA transfer portal on April 16, 2020.

On September 2, Newman announced he would opt-out of the 2020 season due to COVID-19 concerns and began to prepare for the 2021 NFL draft, leaving Daniels to compete with Mathis, Bennett and Beck.

Still, head coach Kirby Smart named Daniels the backup quarterback behind Bennett, who replaced Mathis due to poor play against Arkansas.

Daniels was named the starting quarterback in the game against the Mississippi State Bulldogs, after Bennett sustained a shoulder injury against the Florida Gators.

Daniels' last appearance came against the Charleston Southern Buccaneers on November 20 during senior day (the last home game of the season), and threw 7-for-12, gaining 73 yards and a touchdown during his brief stint.

Following Georgia's national championship and Bennett's affirmation to play out his final season of eligibility in 2022, Daniels entered the NCAA transfer portal.

[31] On September 10, 2023, Daniels led the Owls to a 43–41 victory in 2OT against the Houston Cougars in the Bayou Bucket Classic, throwing a career-high 401 yards and three touchdowns.

In the second quarter, he was hit by linebacker Ahmad Walker, and even threw a touchdown pass two plays later, but after being assessed with concussion-like symptoms, he did not appear for the team in the second half.
