Twenty-four hours after Ohio State lost to Clemson in the College Football Playoff, former Buckeyes' defensive end Nick Bosa helped San Francisco clinch the NFC's 1-seed in the NFL Playoffs.
Bosa is the only former Buckeye on the 49ers' active roster, but he's one of 19 former Buckeyes on active rosters of playoff teams, the most of any college football team. There's at least one former Ohio State player on nine of the 12 playoff rosters, including five on the New Orleans Saints and three on the Houston Texans.
Alabama (17) is the only other team with at least 15 players, though three teams — Clemson, Stanford, and Florida State — have 14 apiece. Nine other teams have at least nine apiece and 35 more teams have at least five apiece. Cincinnati (seven) has the most players among Group of Five teams, while North Dakota State and Southern Illinois (three apiece) have the most among FCS teams, and Grand Valley State and West Alabama (two apiece) have the most among Division-II teams.
One hundred and seventy-four college football teams have at least one player, including two teams in Canada: University of Manitoba and McGill University.
