Deitsch said what I would have, given the chance. I did radio play by play for many years, and the difference between my better broadcasts and the ones that made me cringe on replay was often the level of partnering with the color analyst. I can describe game action with clarity and relative ease, but the explaining of that action is difficult and takes someone who not only knows the X and O, but also someone who has the focus and language skills to clearly explain actions in the tiny time windows that the game action provides. Of the two roles, analyst is more difficult, and it isn't even close.
Doris Burke is a real pro in my book. That she takes great care in her voice, diction, emphasis, fluency and literate style is what sets her apart. Some of her in-game tributes to Geno and the Huskies are amazingly artistic. Her rebuttal to Muffet's remark about "loss of class at the top of the game" during the NCAA finals was a classic.
Of course, opinions vary. That is a given. But if I were still professionally training young sports broadcasters, I would use Doris (and Kara, Rebecca, Kerith, and Megan) as positive examples.
