The BIGGEST coach in football history 😱🤯 Standing just 5 feet 10 inches tall but reportedly weighing as much as 500 pounds (though unverified), Mark Mangino was a coach impossible to miss on the sidelines. In 2007, Mangino led the Kansas Jayhawks on one of the most improbable runs in college football history — a 12–1 season, capped by a 2008 Orange Bowl victory over Virginia Tech. The Jayhawks soared to #2 in the national polls, the highest ranking the program had ever seen.
