FILE - Iowa State quarterback Brock Purdy (15) is sacked by Oklahoma linebacker Nik Bonitto (11) during the second half of the Big 12 Conference championship NCAA college football game in Arlington, Texas, in this Saturday, Dec. 19, 2020, file photo. Bonitto is well aware that the Sooners defense, for all the drastic improvements made over two seasons with its “Speed D” scheme, needs to prove itself outside the Big 12. After winning a sixth conference title in a row, the No. 8 Sooners (8-2) will again end the season in a New Year's Six bowl game against a high-powered SEC offense. This time they face national passing leader No. 10 Florida. (AP Photo/Jeffrey McWhorter, File)
