Travis Frederick is ready to prove he's worth the first-round pick the Dallas Cowboys used to get him. He figures he first has to prove he's worthy of a starting job.
The former Wisconsin center opened rookie minicamp Friday by saying he's "going to have to fight" for a spot on the Dallas offensive line.
Plenty of eyes will be watching because critics say Dallas didn't get enough value in trading down to get Frederick. He says he thinks he "can prove some people wrong."
The 6-foot-3, 317-pound Frederick spent most of his first Cowboys workout at center. Dallas still wants the flexibility of him at guard, which he played earlier in his college career.
