Grand Slams should adapt the Master Series format
Seriously, what's the point of playing all these extra rounds? All you're really doing to the top players is waisting their time by making them go for several extra hours on the court. It's obvious these mental midgets won't do anything to them. What we saw today I wouldn't even call "choking", you're giving them far too much credit by using that word. It's merely become expected for things to unfold the way they have, as they did in the Fed and Murray matches, for example. These men don't belong at this level, really. It's not a knock on them, everyone has their limits, and there is a reason why we don't see them at the MS events. Give the top seeds byes in the first round, invite only the top players, and keep it best of 5 of course. Tournament would be shorter, of much higher quality, and most importantly, competative. Seems simple enough.
