Pro doubles went through a significant change in their scoring (no-add scoring and match tie-break for third setup in lieu of playing the third set) to supposedly make it more "sellable" to tennis tournaments and place these matches on stadium courts more often, and to have them aired on television more frequently.
I don't believe either has really occurred?
In USTA sanctioned leagues, typically there are three lines of doubles and two lines of singles. So, 75% of the players are engaged in league doubles for each match.
I firmly believe more doubles matches should be aired.
Also, there's an old saying, the best doubles team is "McEnroe and anyone". Would it be possible to air some old great McEnroe/Fleming matches???
Tennis Channel, I enjoy seeing the "Classics" matches with Laver, Borg, Conners,McEnroe, Navratilova, Everett, etc...and the Champions tour, and the WTA matches. I think comparing the Classic matches to modern tennis, can really show how much the game has changed just within the last 40 years or so.
I also like all the live coverage on the Tennis Channel and replays of the really good matches.
