Wallace, a dynamic and physical wideout, made his mark in Oxford as a reliable target and explosive playmaker. Known for his ability to stretch the field and create yards after the catch, he became a key piece of the Rebels’ offense during his time with the program.

Wallace started 15 games over his one season in Oxford, after transferring in from Penn State where he started 21 games across four seasons. He notched 61 catches for 934 yards and four touchdowns at Ole Miss. At Penn State, he recorded 145 receptions for 2,155 yards and 10 TDs.

Standing out for his athleticism, the 6-foot-1, 200-pound Wallace consistently presented matchup problems for opposing defenses. Whether working downfield or fighting for extra yardage after the catch, he brought a toughness and versatility that fit well in Ole Miss’ high-powered attack.

During his career, Wallace showcased flashes of big-play ability, turning routine catches into chunk gains and providing a spark in critical moments. His physical style and willingness to compete in contested situations helped him carve out a steady role in a deep receiver room.

Now, he’ll look to translate that skill set to the NFL.

Signing as an undrafted free agent often comes with a different path, but it’s one that has proven successful for many players willing to embrace the challenge. Wallace will have the chance to compete for a roster spot in Arizona, bringing his playmaking ability and work ethic into a wide receiver group looking for depth and versatility.

For Wallace, this next step is about opportunity — a chance to continue developing, to compete, and to show he belongs at the highest level of the game.

And for Ole Miss, it’s another name added to the growing list of Rebels chasing their NFL dreams.
