NORMAN — Daniel Brooks knew it just wasn't his day.
The former Oklahoma running back had a frustrating workout at Oklahoma's Pro Day on March 8. He wasn't running as fast as he could. His movements were not as crisp as he expected. While other players shined, he would walk away from each drill shaking his head, wondering why he wasn't at his best.
At one point, Brooks dejectedly walked away thinking the workouts had ended, something he was ready to be finished with regardless. But two minutes later, after looking back to see Joe Mixon and Samaje Perine still running passing routes, Brooks sprinted across the indoor field realizing he still had to run one more set of drills.
