I cannot believe that people who couldn't see their own genitals beyond their belly could possibly knock someone who had won a bronze medal in the Olympics in any discipline.
To get to the elite in sport you have to be ridiculously dedicated and talented. To get on the rostrum at the Olympics, 99.9% of the population has no chance, regardless of how much they love sport.
I've seen with my own eyes, because I played against them, how good people are who are ranked 150 in the world at tennis. I used to play with Andrew Richardson (former world number 133, British number 2 and best man at Tim Henman's wedding) when I still had hopes of playing professionally. I gave up because I reflected that this guy was 7 inches taller than me, had a serve like a rocket, had massive athletic advantages, consistently hit the ball 10-15 mph harder than me, and didn't make mistakes.
I don't know as much about what it takes in other sports, but I know enough to be certain that people standing on the rostrum with a medal around their neck are bloody good and almost beyond criticism. Maybe if Usain Bolt gets a bronze you can say he's underperformed, but I don't see how you can possibly criticise these people when you could stop 10,000 people in the street and be almost 100% certain that none of them would have an Olympic medal, nor would they ever have the remotest chance of getting one.
