Travis Frederick, C, Wisconsin Badgers (6-4, 338 pounds)
Clearly, the Cowboys wanted to add a physically dominant interior lineman as that describes Frederick to a tee. He is not a top athlete, but he is a functional player who uses his ability to physically dominate his man at the point of attack to make up for it. Frederick makes it look easy stopping power rushers in their tracks and getting movement on in-line run blocks with surprising ease. He started at guard and center during his career at Wisconsin, so he could start at either spot for Cowboys.
