I think it is short sighted to say that requiring players to play 17 tournaments is too much. I mean really, look at it this way:
For a top female player, a schedule more or less along these lines:
Open Gaz or Proximus Diamond
One of those in the Middle East
California Tier 1 or Miami
Rome or Berlin
Acura or Rogers
Obviously spacing would have to be taken into consideration. If you take those 17 tournaments, 8 weeks for the slams, 13 weeks for the other tournaments, then its 21 weeks. Tennis players are independent contractors. They play for money and glory, but they should be smart about it. the only argument i think is right is that the season ends too late in the year. A end of around October would allow people to rest, and start training for new season.
But then again the same people do not rest. They spend the whole time playing exhibitions for money!
Take care of your character. Reputation will sort itself.
