Gavin Escobar is five pounds heavier than he was at this time last year. The Dallas Cowboys’ second-year tight end is weighing in at 254 pounds, and he feels much stronger than when he entered training camp as a rookie. “I know a lot more of it is just strength,” Escobar said. “That was more important for me to just get stronger to help out in the run game.” In May, Cowboys Pro Bowl tight end Jason Witten said he was proud of Escobar for adding strength and working in the off-season to become a better blocker. Escobar was on the field for 207 snaps last season. His 2014 goal is to see that number increase.
