Mike Gundy, one of college football’s most colorful coaches over the last two decades, has been fired at Oklahoma State, according to multiple media reports. Oklahoma State did not immediately respond to a request for comment. As late billionaire T. Boone Pickens poured millions into the program, Gundy turned Oklahoma State into an unlikely powerhouse that often affected the national championship race. After a bye week, the Cowboys lost at home to Tulsa for the first time since 1951. Oklahoma State hosts Baylor on Saturday.
