James Casey is a little frustrated.

He’s paid his dues the last four years working his way up from being a fifth-round draft pick in 2009 to a starting job with Houston. He’s contributed on special teams shown his versatility and done whatever he could to help his team win.

But he’s hardly played since signing with the Eagles this offseason and doesn’t have a catch through three games.

“Of course I wish I’d be out there making catches making plays. Everybody wants to do that” Casey said after Thursday’s practice at the NovaCare Complex. “Of course I want to play. I want to be on the field. I want to be starting. … But a lot of that stuff is out of my control. I’m just focusing on what I can do to help the team win in whatever aspect that is on the practice field or special teams whatever they ask me to do and have a good attitude about it and just keep giving great effort … That’s all I can do.”

Casey’s frustration stems from the Eagles’ overall reluctance to get the tight ends involved in the passing game through three weeks a relatively surprising development. Eagles tight ends have combined to catch just eight passes on 15 targets. But it appeared first-year coach Chip Kelly was putting a greater emphasis on the position after drafting Zach Ertz out of Stanford with the 35th overall pick and making Casey one of his first free agent acquisitions.

“We have plays designed for the tight ends” Kelly said. “I mean right now we’re not sitting in our offensive staff room saying we’re not getting a lot of production offensively. I think we’re running the ball very effectively and throwing the ball very effectively.”

That much is true. The Eagles are second only to the Denver Broncos this week’s opponent in total offense and tops in the NFL with an average of 209 rushing yards per game on 95 attempts the fifth-most in the league. That heavy emphasis on the run has come at the expense of the passing game. Philadelphia ranks 13th in passing yards with 252.7 per game but has attempted the fifth-fewest passes in the league.
