Ertz a potent weapon in Eagles' attack

Tight end Zach Ertz performed admirably as a rookie for the Philadelphia Eagles.

A second-round draft pick from Stanford, Ertz had 36 receptions for 469 yards and four touchdowns. Of those 36 catches, 22 came in the second half of the season.

Ertz is looking for even more production in 2014.

"I think you kind of saw (what I can do) in the second half of the season,” Ertz told CSNPhilly.com. “I was used all over the field, so hopefully it’s more of that."

Ertz combined with Brent Celek to form a solid one-two tandem at tight end. In coach Chip Kelly’s high-powered offense, tight ends have to be ready at all times.

"Brent and myself, I think we can line up all over the field," Ertz told CSNPhilly.com. "Obviously if you look at the two of us, he’s more of a traditional in-line tight end, but in this offense you have to be able to do both. I think that’s kind of what helps us with the speed of this offense. If you want to play fast, you can’t be subbing guys in and out. With the tight ends that we have, we’re able to do that whether it’s in-line or out wide as a receiver."

Even though the Eagles lost wide receivers DeSean Jackson and Jason Avant, there are still plenty of weapons on offense, which includes running backs LeSean McCoy and Darren Sproles.

"We've added a lot of new faces on offense, but at the end of the day a lot of the receivers and tight ends are interchangeable,” Ertz told CSNPhilly.com. "Whether it is receivers, tight ends or running backs, you have to be able to play all over the field. That’s a big thing for me and everybody else."
