I've had this idea for a while, but check it out and please comment. I think that if tournament directors extend the length of a tournament to 1.5 weeks, and start off the tournament with doubles on the first half week, then go into singles draw, it would give more time for players to play both doubles and singles and not worry about getting too fatigued. Also, since they won't be too tired due to the new plan, the tournament directors could make all the seeded players to enter into doubles draw. This plan would inevitably make some tournaments overlap or be very close, but an integrated points system that incorporates both singles and doubles results (I have NO IDEA how this would work) could entice people to play an entire tournament in both singles and doubles. IF this could be achieved, doubles will get more interest (as it did for Nadal-Moya v Federer-other Swiss match) due to the fact that more names will be playing doubles. The seeding system and balance between doubles and singles specialists could be resolved if ATP and other tennis organizations put their minds to it, I'm sure. What do you think? edit: just mentioning that according to the plan above, the doubles final and singles final will be held on the weekends, so people can come visit more.
