Grier was offered scholarships to play football at Auburn, Arkansas, Florida, North Carolina, Tennessee, and Wake Forest. He committed to play quarterback at the University of Florida.
Grier competed with Treon Harris to be Jeff Driskel's backup as a freshman in 2014, ultimately redshirting the season.

Grier received a one-year suspension, effective October 12, 2015, after it was revealed that he had tested positive for performance-enhancing drugs. He said the positive test stems from the drug Ligandrol, and that he was not aware it was banned, while also admitting he never followed protocol to clear the supplement with team trainers. His appeal was rejected by the NCAA, and he would not be eligible to return until the sixth game of the regular season in 2016.
