Sadly, the means justify the ends. In the pros, there is just too much money to be made and overall, it's now America's favorite past time surpassing baseball. I myself has played football all throughout my adolescence and into high school and can argue that it's the best team sport without question. To generalize, audiences watch the NHL for the fights, NASCAR for the crashes and the NFL for the big hits. As a civilization, we're not much different than the Romans and their colliseums. Why do we all slow down when passing by a car wreck? Sad but true.
