I think Randy Pedersen is a great color commentator. He really got pumped up about the matches last week, and you could tell it.
Jim Kelly is okay as a host, I think. You need someone who doesn't know everything there is to know about bowling, to come up with questions for the Pedersens and Holmans, that explain the game to those who aren't that familiar with it.
I agree with you that Kelly needs to stop drawing comparisons between bowling and golf. As someone on the PBA board said, "Enough with the [censored]' golf!"
