Eric Gray began his collegiate career at the University of Tennessee, in 2019 and 2020 he shared a backfield with now Minnesota Vikings runningback Ty Chandler. The duo combined for over 1,400 yards from scrimmage in each of the two seasons, before Chandler transfered to North Carolina, and Gray to Oklahoma. After being tabbed as a ESPN Top 300 prospect coming out of high school, transfering or being a back-up likely didn't cross Eric Grays mind until it happened. Gray had offers from Penn State, Michigan, and LSU, among others. After transfering to Oklahoma, Gray found himself behind fourth year workhorse Kennedy Brooks, how later finished with over 1,000 rushing yards for the third straight season. In 2022, Gray finally got his opportunity to burden the load under a new regime, and he did the most, finishing with 1,595 total yards from scrimmage and 11 touchdowns, Gray finished with 33 receptions, and although Oklahoma had it's first losing season since 1998, Gray received the ever important Reece's Senior Bowl Invite.
