What do most of you believe is the hardest thing in the sports world? Most sports people generally think hitting a baseball is the hardest thing (M. Jordan couldn't do it very well) but maybe in the future some will come to think that stopping a takedown from a groundfighter might be the hardest thing to do in sports. Anyone agree?

[Mr.Totality]

I go with baseball as well.

I would say not turning into a complete asshole once you become rich and famous.

Seriously, probably Golf if you consider it a sport.

Balancing training and the rest of your life.
Also in the same vein, having to work and train

I would say decathalon since it requires a number of different skills. Of course, it could be argued that that's ten things instead of one...

I'm going to go with what I've found to be hardest: volleyball. Can't do that for shit.

The Kyokushin Karate 100-man Kumite. I shit you not. Google it if you don´t believe me.

It´s the ultimate test of endurance, skill, cardio and pain tolerance. 100 2-minute full-contact Kyokushin rules sparring matches in one day.

Only a handful of KK blackbelts have successfully completed it, and ALL of them have gone straight to the hospital afterwards - except Francesco Filho of K-1 fame, who has done it more than once(!).

flying armbar

[Igorot Warrior]

Probably not the hardest thing to do...but I'm still amazed when I see a basketball go in the hoop cleanly ("swish") from behind the three point line...or from a fade away jumper.

[Cartola]

Running 400 meters under 45 seconds is for mutants.

[Captain Blamo]

Golf

I've played golf and I've watched TV pro's live and all I got to say is that those guys are good.
