A former quarterback, he played his first three years of college football at Florida and transferred to Arkansas for his final season.

As a redshirt freshman in 2017, he was named the starting quarterback heading into Florida's season opener against Michigan, beating out 2016 starter Luke Del Rio and incoming Notre Dame transfer Malik Zaire.

[5][6] Franks struggled in the game against Michigan, and was benched in favor of Zaire in the second half after completing 5 of 9 passes for 75 yards.

[12] In the Gators' third game of the season against Kentucky, Franks was carted off the field with an apparent leg injury late in the third quarter.

[13] Florida head coach Dan Mullen said after the game that team doctors believed Franks suffered a broken ankle and would likely miss the remainder of the season.

[26] He was named the third-string quarterback behind incumbent starter Matt Ryan and second-string backup Josh Rosen.

[27] Franks made his NFL debut in Week 11 during the Falcons' final drive against the New England Patriots.

The turnover marked the fourth consecutive Falcons drive to end with an interception, following two thrown by Ryan and one returned for a touchdown from Rosen.

[28] In June 2022, Franks began taking reps at the tight end position, with the Falcons announcing they were planning to use him in a hybrid role.
