Why should they play more doubles? Seriously? I mean, half the time we don't even see doubles on television; the money for the double's event isn't that great; they are already multi-millionaires...so other than playing MORE (a complaint the top guys already have)....then what would be the benefit from their stand point?
The women are different in that all of their events are best of 3 any way. If the top guys decide to play doubles, I would actually feel sorry for their partners because the first time their single's match have to go over 4 hours...then they are scheduled for a doubles event the same day...how much would you bet they would probably pull out of their next double's match. So no...I really don't see the top guys playing more doubles at all. Just my opinion.
