"Many parents face a more practical question: Should our kid play football?"
I am sure we are witnessing the Golden Age of professional football. I think the blossoming of the passing game is directly correlated to efforts to reduce the violence of the game - a preemptive effort against more and more parents, mothers in particular, who are going to start answering this question in the negative and discouraging dad from watching "that barbaric sport". When we see Mothers Against Head Injuries - it'll all be downhill.
Enjoy while it lasts.
