Walthall spent three unproductive seasons at Hawaii before transferring to Incarnate Word in 2024. He posted a career-best receiving line, 85/1,290/14, that year, setting his new school’s single-season receiving yards record along the way. He measured 6’1/191 and produced a 10’1 broad jump at the NFL Scouting Combine before leaping to a 38.5” vertical jump at Incarante Word’s Pro Day. Walthall earned first-team All-SLC honors in each of the past two seasons and earned first-team All-American honors in 2025 despite missing two games with a shoulder injury. He has a chance to make the active roster.
