Morris Claiborne had to do a couple of things this spring.

One, get bigger.

Two, get stronger.

So far, so good.

“I feel like I’ve had a tremendous offseason with getting in the weight room and trying to get stronger,” the second-year cornerback said Tuesday after the Cowboys’ first OTA practice at Valley Ranch. “Actually, I put on a couple of pounds. Last year, I was at 187. Now I’m at 193. So I’m just trying to learn how to move with that weight and just get comfortable.”

Claiborne and the Cowboys figure he can use the extra weight to become a stronger tackler, a skill that will be required more from the cornerbacks under new defensive coordinator Monte Kiffin. Last year as a rookie, Claiborne never got up to speed with his strength because he spent the spring recovering from wrist surgery.

“There were times last year where he wasn’t strong enough to execute a certain technique,” secondary coach Jerome Henderson said. “So he had to get stronger to do that. He’s done the work to do that.”
