Keep Doubles Promote Doubles
I have an easy suggestion to help with viewership and another one that’s just an observation.
Have each team wear at least matching colors different from the other side of the net. We’ve all experienced difficulty even in singles when the players have same kit AND hat!! If you flip on the tennis channel you will immediately see two pairs rather than four players. Easier to follow. And new fans are already trying to figure out scores.
My second is that many players team up for a tournament one and done. Fans don’t get to know them and are less likely to be invested over a season. I do not think Bryan Bros were popular just because they were winning. They were a team and looked like a team and you knew which on side of the net were the Bryans. Not sure this is fixable, but that’s a lot of why I think many are interested in known pairs or novelty star teams.
