I'll say this: To your point, I will admit that I withheld a similar constructive criticism.
I have been watching CCDG vids for a while now and, at first, I found the Cali surfer (cool dude) thing to be a bit distracting and a little shticky. But hey, I'm a southern boy with a drawl, so I chaulked it up to diversity or whatever. It also made me feel old, like I was too mature or not hip enough to watch. All that being said, I have come to find their colloquialization completely genuine, endearing, and furthermore a bit refreshing when oposed to the "norm" of sports commentary.
To me that is exactly what makes them unique and iconic. Its kind of the "hook", if you will, to use a music term. If it were done in the same voice like professional golf, for example, I would likely fall asleep watching. The overwhelming positivity that comes through is also nice. I'm super competitive, and partially why I don't follow sports like I used to is that it keeps my blood pressure down lol. The commentary of NFL football for example highlights the drama, controversy, and aggressiveness of the sport. While this also serves to hook viewers, its not what I want out of Disc Golf. Disc Golf has served as a sport to feed my competitive spirit, while also offering serenity. I'm glad that CCDG is able to capture that Spirit of the Sport within their commentary. Everywhere I have played DG the folks I have met represent a "brotherhood" type of sport with a sense of community more than any other sport I have participated in. I also feel like this is captured in the commentary of CCDG better than others I have seen.
