Eagles tight end Zach Ertz has never caught a pass from Sam Bradford in a game -- or in a practice, for that matter -- but Ertz has played catch with his new quarterback and apparently, Bradford has a rocket arm.

During a recent interview with CSNPhilly.com, Ertz said that Bradford has a stronger arm than any quarterback he's ever played with, including Andrew Luck, who threw passes to Ertz for two seasons at Stanford. 

"We've been throwing for the past three weeks and I can honestly say I've thrown with Andrew, Nick [Foles] and other guys, and I don't think I've thrown with a guy who has a stronger arm than Sam Bradford," Ertz said.

The craziest thing about Bradford's arm strength is that he's been able to show it off despite the fact that he still doesn't have his "full legs underneath him." The Eagles new quarterback is still rehabbing the torn ACL he suffered in his left knee back in August, an injury that cost Bradford the entire 2014 season. 

"He hasn't been able to really truly get his full legs underneath him," Ertz said. "But the ball still comes out effortlessly, and it's a lot of fun to run routes with him."

Bradford might be fun to run routes with and he might have a cannon for an arm, but does that mean he'll be successful in Philadelphia? 

Not necessarily. First of all, Chip Kelly could trade Bradford tomorrow because with Chip Kelly, anyone on the Eagles roster could be traded tomorrow. 

Secondly, having a strong arm in the NFL is kind of overrated, at least according to Luck's backup quarterback, Matt Hasselbeck. 

"Arm strength, I think, is a thing that's like incredibly overrated in the NFL," Hasselbeck told the New York Post during the 2014 season. "Andrew doesn't need arm strength because of the other things that he has, but he also has it."

So that settles it. Unless it doesn't.
