The Cowboys haven’t earned much praise for their decision to draft Wisconsin center/guard Travis Frederick in the first round of last month’s NFL Draft. True, Frederick helps ease some of the personnel pressure along an offensive line that struggled mightily in 2012, but scouts and analysts have labeled him – who most (including Frederick himself) figured would go in the second or third round – as a reach at No. 31. But that didn’t seem to be weighing on Frederick much as he arrived at Valley Ranch for Cowboys rookie minicamp this weekend. “I think for me, it’s just about going out and playing the way that I played in college and the way I know I can play, and take advantage of the great coaching,” Frederick said during an interview with reporters. “Like I said, [offensive line] coach [Bill] Callahan’s a tremendous coach and I think he can make me a lot better player than I have been. So if I can just work as hard as I can and take advantage of his coaching, I think I can prove some people wrong.” Though Frederick admitted to feeling “a little bit” of pressure to make a good first impression on Callahan, he said he didn’t do anything special to try to impress his new coaches.
