PHILADELPHIA (CBS) — In his first season as head coach of the Philadelphia Eagles, Chip Kelly surprised everyone and led the Eagles to an NFC East division title, earning them a home playoff game. Kelly’s often scrutinized, fast-paced offense finished second in the NFL in yards per game (417.3) and fourth in points per game (27.6).

Second-year Eagles tight end, Zach Ertz, says the offense is confident they can be even better.

“Last year, 10-6 in the regular season and from an offensive standpoint we know that we can be so much better than what we were last year and that’s kind of all we’re focusing on right now, is getting better as a team,” Ertz said Tuesday on the WIP Morning Show.

The Eagles, including Ertz, have embraced Kelly’s new-school practice style and coaching techniques.

“The common goal for every team is winning, but I think Coach Kelly does an unbelievable job of laying out the plan each day and how we’re going to attack each day and there’s a routine and familiarity that we all have,” Ertz explained. “It just makes the process more enjoyable when it’s done like this.”

The Eagles head into the 2014 season without their best receiver and most dynamic play-maker from last season, in DeSean Jackson. The Eagles released Jackson, now a Redskin, at the end of March.

“Not many people are thinking about DeSean right now over in this building,” Ertz said. “I mean, DeSean was great to me, but at the end of the day we are very satisfied with the players we have on this offense.”
