FILE - In this Sept. 17, 2016, file photo, Oklahoma offensive coordinator Lincoln Riley, right, talks to quarterback Baker Mayfield (6) during an NCAA college football game against Ohio State in Norman, Okla. Riley has taken some of the air out of the Air Raid, and the results have been spectacular.. Once Riley put a little more ground and pound into Oklahoma’s high-octane attack, everything clicked. He ran into problems this year against Houston and Ohio State, but again, bounced back with the ground game. (AP Photo/Sue Ogrocki, File)
