its hard to say. Certainly they bulid up a lot more speed in hockey before hits, but they also don't have to go across the middle, GET AIRBORN, and then get popped. I'd say hockey players are tougher, but at least in hockey it's possible to play the game somewhat gracefully, where there doesn't have to be huge hits every 30 seconds. In football, somebodies getting hit every play. But because of the speed involved, i'd say hockey is the more dangerous.
