Crazy Carl - Toughest Athlete in Sports?

Recently Sports Illustrated ran an article called The 25 Toughest Athletes (link to article). Carl and I had some discussions about this list and about how absurd it is. How can you name an athlete who plays in a non-contact sport the toughest athlete?

Anyway, here's the first IM I received from Carl today:

(that's Carl's real screen name. Feel free to IM him and call him names)

RUCameron77 (11:02:27 AM): the masters started today. already one golfer had his arm broken, another got paralyzed, and another broke his leg so badly that the broken bone came through the skin and was sticking out.
RUCameron77 (11:02:58 AM): oh wait, that didn't happen in golf... because golf isn't tough, isn't a "sport", golfers aren't tough, and tiger is a big fat pussy

Oh Crazy Carl, you're crazy!
