It's crazy to think that events which have had historic performances in the past (10k, 200, shot) are on the chopping block. And I am not sure what the reasoning is behind eliminating them.
That being said ... I'd axe the 200, 10k, TJ, and race walk before touching the shot put. The others are variations of other events. (Sprint, middle distance, long jump, and walking.) The previous poster was spot on when he said that these events require hardly any additional training.for a sprinter or a runner. (Or jumper/walker to a similar extent.) Seriously, if you've ever sat through heats of the 200 at Penn Relays or waited until midnight to watch or run a 10k, you might see what I'm getting at. "Awesome. People who couldn't run the 100 or the 5k." There's plenty of options for long races on the roads ... they're called marathons, and to the elite, they're more important than the Olympics.
On the other hand, the shot put is an event in itself. If there's any equipment-based competition more basic than throwing a rock as far as you can, I don't know what it is. It is ALSO and most importantly the only Olympic throwing event that can be done inside somewhat safely. If anything, I'd cut the hammer (shot put on a string? With a movement that necessarily mimics the turns of discus.) (I wouldn't miss the weight throw, either, but it's not Olympic.)
But I digress. The real point is that the decision should not be based on which events are the most popular. Shoot, if you added a 150m people would watch Usain Bolt or "the next Usain Bolt" run it. The decision should be based on giving young athletes around the world a variety of athletic events.to aspire to be great at. GIVEN THAT such a decision has to be made, which of course sucks.
