"Thank you guys for making this one of the best days of my life," Riley said.
In his first year in Norman, Riley helped guide the seventh-best offense in the country at 542.9 yards per game. It was nearly an 80-yard jump from 2014, when the Sooners averaged 464.7 yards per game. Quarterback Baker Mayfield led an offense that threw for more than 300 yards per game and nearly was invited to the Heisman Trophy ceremony as a finalist.
Riley was hired by Oklahoma coach Bob Stoops in January and immediately transformed the Sooners back into a spread offense. His impact was immediate after spending five seasons as the offensive coordinator at East Carolina, where he had one of the top offenses in the nation every season.
It was announced that the voting was the closest in the award's history with a single vote separating first and second. Other finalists included Alabama defensive coordinator Kirby Smart, North Carolina defensive coordinator Gene Chizik, Clemson defensive coordinator Brent Venables and Baylor offensive coordinator Kendal Briles.
"Football is a very humbling game, coahcing is very humbling," Riley said in comments before being named the award winner "The second you have it made, it has a way of reminidng you where you came from."
