Chip Kelly Uses Rocky Balboa, Fresh Prince And Other Philly Icons To Call Plays Vs. Redskins

America got its first taste of Chip Kelly's innovative, fast-paced offense on Monday night.

And after the Eagles' season-opening 33-27 win over the Washington Redskins, it's safe to say we'll be seeing more where that came from.

Among other parts of Kelly's secretive offense that were revealed at FedEx Field, photographers caught Eagles coaches using play cards with images of Philadelphia icons like The Phillie Phanatic, Rocky and even Will Smith's character from The Fresh Prince of Bel-Air.

Kelly uses these play cards to help speed up the offense. When players can look to the sidelines for plays, they won't have to huddle on the field. Kelly's Oregon teams had great success using this system.

While the meaning behind the signs is secretive, Jason Wolf broke down the basic idea in a USA Today story:

"Many of the pictures and signals are intentionally humorous and based on what amounts to inside jokes, which are deviously simple and in effect create a language only players know.

A hypothetical example is a photo of Phil Mickelson indicating a snap count of two, because the golfer often finishes second. And it's based on the concept of a combo meal at a fast food restaurant, where ordering a "No. 2" at McDonald's gets you a Quarter Pounder, medium fries and a drink."

Wolf writes that ESPN hired a mathematician along with a team of photographers to try and break down Kelly's system during Oregon's 2011 BCS National Championship faceoff with Auburn. And they were unsuccessful.

So opposing defenses truly have their work cut out for them this season.
