Cav wimped out basically. He said it was too dangerous and didn't sprint. Maybe that was a sensible decision, maybe not. But he also made some rather silly comments about people who aren't sprinters sprinting which seems to get very close to the saying that people should get out of the way for him. It is a race. So long as you don't do anything that is against the rules, you do what you can to win. No-one has any special right to contest a sprint. He still needs to do a little growing up. But he will.
