However your comments about hockey show you are the one on full retard. First off, the vast majority of people in the US couldn't play simply because they can't skate. That in of itself makes it far more difficult to play. Throw in the need to stick handle, the physical play, the no out of bounds, the fact there is a player specifically out there to stand in the net and prevent you from scoring. It's not even close at how much more athletic ability is needed to play hockey. And as for the smarts, well teams teach systems, but the systems on the defensive side are a reaction of what the offense is doing. You could break down a NHL game and never see the same play twice. It's read and react. No other sport has the same dimension.
