He’s got some explaining to do. The Sooners running back, who was suspended for the 2014 season for punching a woman, says he’ll be honest and remorseful when interviewing with NFL teams. He tearfully apologized last month after his attorneys released surveillance video showing the victim shoving and slapping Mixon before he slugged her, breaking her jaw, eye socket and cheekbone. Despite an outcry, Mixon remained on the field, scoring two touchdowns in Monday’s Sugar Bowl. The incident is expected to knock him out of the first round of April’s draft.
