I feel the most intriguing point would be the eventual culture change that it might create. Imagine a premium on wrs and rbs and the possibility of putting less emphasize on the stereotypical qb in the league. Could you imagine with that system in place taking a qb in the 3-7 round as big time playmaker. They would certainly be available. I feel the thing that could make it successful is ownership and management being behind a change in customs. All the sudden a qb in that system is valued like a rb. Management would have to fully embrace change and the way they draft as well. And they can't resort back to old ways of thinking what an NFL offense looks like.
I feel the fast pace would need tweaked due to the depth/numbers of the defense in the NFL. And ultimately I believe that at the end of the day a strong defense wins out. Offenses of any sort just need to be good enough to score like 21 to 28 on given nights and let the defense hold. So maybe the pace slows down to the way hurry up offenses in the NFL work nowadays.
Idk. It'll probably fall hard but i guess i just want the NFL to become as diverse offensively as college has become. It would just be intriguing if a team would fully embrace the change that would come along with a guy like Chip Kelly.
