We give too much credit to this "fast-paced offense" thing for Kelley's success and not enough to great playcalling, schemes, and coaching. The innovative plays he runs and the reads he gets his players to make, as well as his thought-out practice schedule are what sets him apart. Fishduck.com has a great series of videos explaining Chip's offense simply and you can really see the mastery behind it.

That's just what I've learned from my small studies of the game, I might be way off as I am no football expert.
