Only one year into his tenure with the Philadelphia Eagles and Chip Kelly already leads the NFL in innovation.

The 50-year-old has implemented his unique system on the field as well as off of it, where he's created personalized smoothies for players and implemented a scientifically sound music selection at practice.

And now, from the Eagles' off-season workouts comes a story of Kelly using technology to simulate motions and routes at practice.

In a recent Philly Mag story, Eagles rookie nose tackle Beau Allen told Tim McManus that Kelly is driving around a remote control RV at practice.

"I was sitting and waiting to go in and meet with [Howie Roseman] and all the front office guys, and Coach Kelly was driving around a little remote control car – they use it out on the field because they can't do motions -- and he drove it right into me and was like, ‘Oh, hey Beau, how are you doing?’ And I was like, 'Hey, Coach.'"

At first, some people assumed Kelly was using this device because coaches are prohibited from being on the field during Phase One of offseason workouts. But Eagles blogger Mark Saltveit cleared the air when he reported that the RV was actually employed during Phase Two practices. This likely means that Kelly isn't cleverly attempting to skirt NFL regulations, rather he has simply found a new way to engage the defense.

Why Kelly is using RVs rather than humans, and how these devices help the defense, remains to be seen. And knowing Kelly's secretive manner, we may never find out.
