(NYPOST) — He’s a force, a 6-foot-4, 400-pound man-child.

But you won’t see Tony Picard battling in the trenches. The Washington prep star, known by friends as “Big Tone,” is a converted fullback, and he’s thriving at his new position.

The White Swan High School senior began his career as a lineman. He still plays nose tackle, but the agile and surprisingly quick for his size big man has become a factor out of the backfield, running for more than 500 yards and eight touchdowns this season, according to BustedCoverage.com.

“I just love carrying [the ball] and hitting people,” he told The Post in a phone interview Saturday night. “I’ve enjoyed it. I love playing on a line, I enjoy running the ball. I do what coach asks.”
