Appalachian State Defensive Lineman Turned Oklahoma State Offensive Lineman Primed for Breakout Season
20 Aug
Summary
- Markell Samuel switched from defensive line to offensive line at Appalachian State
- Samuel is now a sixth-year senior and poised to start at left tackle for Oklahoma State
- Samuel brings experience and technical expertise to an inexperienced Cowboys offensive line

Markell Samuel's journey to becoming a potential starting left tackle for the Oklahoma State Cowboys is a testament to his versatility and determination. Initially a basketball player, Samuel didn't start playing varsity football until his junior year in high school, but quickly made an impact as a linebacker and defensive end, earning a scholarship to Appalachian State.
However, Samuel's path took an unexpected turn when, ahead of his redshirt sophomore season, he switched positions from defensive line to offensive line. The transition was not immediate, as he saw limited playing time in his first two seasons. But in the past two years, Samuel has blossomed, starting four games at left tackle as a junior and earning All-Sun Belt honorable mention as a full-time starter last season.
Now, as a sixth-year senior, Samuel is poised to anchor Oklahoma State's offensive line, which is one of the biggest question marks for the team heading into the 2025 season. His experience and technical expertise, as highlighted by his teammates, will be crucial in protecting the blindside of the Cowboys' young quarterbacks. With Samuel leading the way, Oklahoma State's offensive line could be a strength rather than a weakness this year.
