LAWRENCE, Kan. (AP) Nobody would fault David Beaty for concentrating entirely on stopping Oklahoma running back Semaje Perine, who reeled off a record 427 yards rushing in a rout of Kansas a year ago.

Trouble is, the Jayhawks' coach has plenty of other things to worry about on Saturday, too.

Like slowing down Baker Mayfield, who threw five touchdown passes in a 55-0 blowout of Kansas State two weeks ago. Or bottling up another freshman running back, Joe Mixon, who carried 16 times for 154 yards and two scores in a 63-27 clocking of Texas Tech last weekend.

Pop the antacids, coach. You might need them.

Ever since their stunning loss to Texas, the No. 14 Sooners (6-1, 3-1 Big 12) have looked like an entirely different team. They led the Wildcats 35-0 by halftime in that blowout win, and scored at least two touchdowns in every quarter of their romp through the Red Raiders.
