I'm not even going to give an opinion, because I don't know enough about whether or not this could even work in the rules, but just give this a look...
On the one hand, I've always been a fan of the idea of teams getting outside of the box. On the other, I don't like the idea of this becoming the next phase in NFL group-think, taking away the conflict at the line of scrimmage that the game has always had at its center. Still, if a team could put together an offense full of speedy athletes, maybe this set is the kind of thing that would allow their gifts to be maximized, and it would be fun to watch NFL defenses figure out the way to break this (much like the Parcells/Walsh duels of old).
