Final answer:
Troy Smith was the last OSU football player to win the Heisman Trophy in 2006. Notable OSU players like Ezekiel Elliott did not win it, while Eddie George won in 1995, and Archie Griffin won twice in 1974 and 1975.
Step-by-step explanation:
The last OSU football player to win the Heisman Trophy was Troy Smith in 2006. The Heisman Trophy is awarded annually to the most outstanding player in college football in the United States whose performance best exhibits the pursuit of excellence with integrity. Although Ezekiel Elliott had an exceptional career at Ohio State University, he did not win the Heisman. Legendary players like Eddie George won the Heisman in 1995, and Archie Griffin remains the only player to win it twice, in 1974 and 1975. Troy Smith, with his superb performance during the 2006 season, including leading his team to the national championship game, garnered this prestigious accolade as the last Buckeye to do so.
