OKLAHOMA CITY (AP) _ Oklahoma running back Adrian Peterson says he has plenty to motivate him this season.
He would like to win the Heisman Trophy, but says beating Texas and winning a national championship are more important.
But he's also hoping his father will be released from a halfway house in time to see him play this fall. And he's pushed by the memories of his grandfather who died recently and his brother who was killed by a drunk driver when the two were riding bicycles as kids.
Peterson says he's working to improve his blocking and pass catching to be on the field every down.
And coach Bob Stoops says the goal is to get Peterson two-thousand yards rushing and about 500 more receiving.
