Grier’s career started at Florida in 2015 after redshirting his first year on campus. He saw action in six games, starting five of those. The redshirt freshman Grier lost the starting job to sophomore Treon Harris halfway through the season. After seeing he wasn’t in Florida’s future plans, he transferred to West Virginia, sitting out a year before returning to the field in 2017 as a redshirt junior.
Dana Holgorsen’s punishing run-first offense was a strong fit for the mobile Grier in 2017. Though his best work was done in the pocket, his ability to rollout and hit receivers on the run opened up the Mountaineers’ offense.
