I hate to bring everybody down, but could someone knowledgeable explain the basics about why and how this offense is supposedly so "complicated"? I mean, it doesn't look all that complicated on the field, at least to this untutored eye. So I wonder if it really is all that "complicated" compared to other NFL offenses. All details and explanation would be helpful. Also, why is this complexity valuable in the NFL? And if it's so valuable, why don't most teams run it or something similar? Or is this "complicated" business just a load (or half-a-load) of hooey? And PS: If this is already explained in detail elsewhere on or off this board, I'd appreciate direction or link.
