Two completely different games IMHO. In US NFL the head/helmet is a weapon, as is the player. Lifespan, both sporting and actual are quite shocking in the pro US game. The players are targeted, with or without the ball. Rugby, for the US members, is a game of playing the ball (supposedly) not a player without the ball. Having said that, I spent a terrible day watching my very good, fast younger son in hospital suffering severe concussion after being targeted by the forwards of the opposition. He plays on the wing, is fast and furious once he gets going. The opposition “took” him out and this is only High School Rugby! I thought we might lose him when he went into terrible convulsions on the field. It is his second serious concussion. Just too fast and commited for his age/wieght. After this we are now in quandary whether to keep him playing next year. I know this isn’t yachting, but got to say this: After this experience I did a bit of research into head trauma amongst sportsmen. The results are SHOCKING with a new research groups underway in the US and Australia. A lot of serious ramifications that affect not just the players but also the people around these guys. I am still a great fan, just see it in another light. These guys are living very dangerously. OK Carl, I will now get back to a boating topic!
