The four Grand Slams, the two tours and Saudi Arabia are all hoping to revamp tennis

Tennis could be on the verge of massive structural change if one of two separate proposals formulated by the four Grand Slam tournaments and the WTA and ATP professional tours ends up moving forward

On this, the leaders of tennis can agree: There is more money out there to be made. And they see eye-to-eye on this, too: The sport's current structure could stand to change.

The how's and why's and when's of it all?
