Well it's the players that make the sport. If the top players who bring the attention and money to the sport are willing to make a stand over how much they have to play in a year then they should be listened too. I'm not saying that there should suddenly be tons of gaps but there's pretty much not break from January till the end of Wimbledon, after the US things are a bit quiter but still a lot of tournaments. Even if there was some way of at couple of down weeks being found in the first 6 months of the tour then it would probably help.
I think Stich should keep his nose out of this and accept that today's players are dealing with entirely different issues. Certainly from next year the players will have a 7 week off-season following the WTF instead of the present 5 (4 if they have to play in the DC finals at the beginning of December), but, as I can't see any tournaments being dropped, it seems that at least two more tournaments will be played back-to-back, and I understand that next year, whether or not it's due to the Olympics, the Paris Masters and WTF are going to played that way, which is particularly unfair at a time of year when the top players will be tired. It's hard enough for them as it is.
What Andy has said, and I'm sure the others might agree with him, is that fewer Masters should be mandatory, rather than just the current one. That would give the players the option of taking a break when they wanted to rather than the schedule having to be revised.
The only thing where Stich makes a point is about the playing of Exhibition matches, but again if players want to play them, well, it's their choice.
