People see how brutal the sport is, but I also think it's a little silly because I'm not sure what these guys will have left in the tank Thursday and I'm not sure what this proves. Apart from the danger, there is a little bit of a feeling that it's not credible. I think triple overtime is great but the 15th overtime, you think maybe they ought to rethink the format. But on balance, it is a good thing. It's a World Cup day and everyone wants to talk about tennis. There is something about this that seems a little unseemly to me, but I just may be a prude.
