MANGOLD'S OHIO STATE CAREER PER Wikipedia:

Mangold attended Ohio State University, and was a three-year starter at center for the Ohio State Buckeyes football team. He was rated on a par with former Buckeye All-American and 2001 Rimington Trophy winner LeCharles Bentley by offensive line coach Jim Bollman. "Most guys you get out of high school have to be taught to play center. He already knew the mechanics of the position. That was a big, big advantage," said Bollman. Ohio State's most durable lineman, Mangold logged over 300 minutes of action in each of his last three seasons.

In his true freshman year, Mangold appeared in eight games as backup for Alex Stepanovich. In 2003, Stepanovich suffered a knee injury in the second game of the season vs. San Diego State. Mangold moved in and started the final 11 games of the season. When Stepanovich returned, he shifted to guard while Mangold continued to man the center position.

He earned second-team All-Big Ten Conference honors in 2004, when the coaching staff named Mangold Offensive Lineman of the Week seven times and Offensive Player of the Week vs. Northwestern. Mangold was again chosen second-team All-Big Ten in 2005. He closed his career with 33 starts in 45 games.
