Here is some of mine.
Now, I am not a fan of pushing (or Wozniacki for that matter) but if it's a gamestyle that works for a player then just let them fricking do it. The hate for pushing on this board (and in the press)is a little ridic. I dont doubt for one second that Wozniackis slump can be partially linked to the hate she receives for playing the way she does which I think is low. Leave her alone.
I would also like to see more carpet tennis events. I know virtually none exist anymore but I loved watching tennis on that surface. It reminds me of a mix of both grass and hard courts.
I've also said this before but I think its ridiculous that three of the four grandslam tournaments are played in a three month time span out of a ten month playing period. I'd like to see the biggest events spread out through the course of the year.
