Cowboys having Zach Martin play some center

The Cowboys have been using rookie Zach Martin at guard this spring even though he was a left tackle at Notre Dame and this week they had him play a little center.

“It’s hard,” Martin said. “I told [starting center Travis Frederick] the first time I was in there and came to the sideline, ‘God, you got a lot going on up there. You’ve got to know a lot.’ Just trying to get better every day but there’s definitely a lot going on over the ball.”

It’s important to be versatile as an offensive lineman in case injuries hit and guys have to be moved around.
