PHILADELPHIA – Zach Ertz made a splash this offseason by saying that Sam Bradford was the hardest-throwing quarterback he’s ever worked with.

Considering that Ertz caught passes from Michael Vick, Nick Foles and Mark Sanchez during his two seasons with the Eagles, that was quite a comment. Throw in Andrew Luck, Ertz’s quarterback when the two were teammates at Stanford, and you really get a pretty impressive list.

But it turns out there’s more. Ertz has gone to San Diego to work out with trainer Todd Durkin during this offseason. Durkin trains Saints quarterback Drew Brees, who was not throwing while Ertz was there.

“He was kind of taking a rest,” Ertz said. “But I threw with [Seattle’s] Russell Wilson. I threw with Andrew [Luck] back at Stanford. Wherever there’s a good quarterback, I’m going to try to go. I just focus on getting open. When the ball is there, catch the ball.”

At the Eagles’ practice Monday, Ertz caught a 50-yard touchdown pass from Bradford during 7-on-7 drills.

“The guy can put it wherever he wants,” Ertz said. “It’s fun running deep and having faith the ball’s going to be exactly where it needs to be. On that 50-yard completion, I didn’t have to do too much – just run as fast as I could. He put the ball exactly where he needed to.”

Bradford talked the other day about building relationships with his teammates. Even though his knee hasn’t been cleared for full participation in practice yet, Bradford said he makes a point of talking to receivers after a play or spending time together in the film room.

“Just coming in here to work every single day,” Ertz said, in answer to a question about what Bradford has done to fit in. “We don’t need him to be a rah-rah guy. We have a lot of rah-rah guys, motivational guys like DeMeco [Ryans] and Malcolm [Jenkins] and some of the guys on offense like JP [Jason Peters] who are going to rile guys up.

“Sam comes in and works every single day. It’s tough being the new guy, especially when you’re a quarterback, and having that leadership role. But he comes in every single day. You see him every day in the weight room, working hard and getting the knee ready. We have all the faith in the world in him.”
