The Saints played right into RG's hands with this thing. The NFL is a money-machine, and the only thing that can rock their boat is the potential lawsuits that are eventual from the quickly gathering scientific data on concussions and head injuries. What they were denying only a few years ago, they are embracing now because the science is pretty clear-cut, and they have to be proactive. The NFL would love to have guys blowing each other up every play, but right now, it's simply business, and people are going to watch anyways, so they have to err on the side of caution.
