"On Wednesday, I relayed to one of those coaches that a couple of coaches who’d played both the Eagles and Kansas City Chiefs said Philly’s offense was relatively simple. He smiled, and said, “That’s the idea.” And it’s a credit to Moore’s ability to take a lot of people, and a lot of ideas, and boil them down to allow for players to play fast and, by the way, score 55 points in the NFC title game."
The article explains a little what is the goal and where the ideas come from.
