According to Rowan Kavner of DallasCowboys.com, even though the Cowboys drafted travis Frederick as a center, they could decide to have him play guard this season with Phil Costa at center.
Obviously, there are lots of things we still need to know about the line. From left to right, there are plenty of question marks but let’s focus now on the middle. The Cowboys drafted the rookie from Wisconsin in the first round, giving us all the assumption he will be ready to take over at center when the season begins. Phil Costa’s 2012 season was hard to dissect, considering he missed nearly all of the year with back and ankle injuries. But he did have a stellar performance against the eventual Super Bowl champion Ravens. Still, Frederick’s draft status suggests he will be the starter – at some spot. Center is most likely but he could also swing out to guard if that proves to be a better fit for the entire offensive line.
Costa did a pretty good job at center last season. Having Frederick play guard, might be the best move for this season.
