Six tight ends have been drafted since Jason Witten was acquired in the third round in 2003. As Witten has rewritten the Cowboys’ record books, he has seen understudies, such as Anthony Fasano and Martellus Bennett, come and go. Now Witten is ready to welcome yet another rookie teammate, second-round pick Gavin Escobar, who plays the same position he does. “It sounds like they were really high on him and think he can be a good player,” Witten said Friday at the Mesquite Boys & Girls Club, where a learning center bearing his name was unveiled. “I’ll do everything I can to help him with that process to allow us to be more successful and give us a chance to win. Ultimately, that’s all I care about…There’s no ego there for me. It’s all about winning and that’s a part of being a leader and a captain, to help other guys play at a high level. There’s no hard feelings from that standpoint.” The Cowboys believe that Escobar can broaden the dimensions of the passing game and improve an offense that was 20th in the NFL in red zone touchdown efficiency. “He can make plays over his head, and we feel like he has the traits to be a ‘Y’ tight end at some point,” head coach Jason Garrett said. “We are excited about the second tight end.”
