Durable, high-IQ Spartan interior lineman with elite experience
In the 2023 season, J.D. Duplain was one of Michigan State’s steadiest veterans, earning All-Big Ten honorable mention while extending his run to 47 career starts and more than 3,000 snaps on the offensive line. His biggest strengths are durability, consistency, and versatility in the trenches—he’s the kind of grinder coaches trust to set protections, communicate fronts, and keep the offense on schedule. If you want a tough, experienced interior lineman who brings leadership and reliability more than flash, he’s a very strong fit.
