Honestly probably watch less tennis...I already enjoy playing more than watching it...and with horrible offerings like the tennis channel it's almost work to find matches you want to see anyway- probably just watch highlights on youtube until the next "Great" sparks my interest.
I am a Hockey guy at the core - tennis was just the sport I needed to stay active and reduce injury- Rafa/Fed made me want to watch, 2008 Wimbledon I caught by chance waiting on a plane...and I was hooked.
had I caught a Murray Novak Match I can't say that I would have been as interested...i would have probably thought...well here is a sport you play until someone misses
so I pretty much owe it to Rafa/Fed for getting me interested in the sport and starting to play it at age 29
