Female Sportscasters-Do They Add Value?

I've been studying female sportscasters since 2000. I've been a member of AWSM. I've written a fictional book about a 17-year-old who wants to become one. I've read various nonfiction books, interviewed countless female sportscasters. Anytime I write about them on my blog, I get men writing in saying, "They're terrible. They're just a pretty face. They don't know sports." 

Who are these women? Why do they do what they do? Is it just a ploy for male attention?Or do they have an aptitude, a talent, a certain intelligence that can only be demonstrated in the male sports arena, particularly football, basketball and baseball.

Are certain women better suited to different settings? Does a certain type of woman belong on the sidelines? Does another type of woman belong in the booth?

Tune in to hear my musings. I may also be interviewing a few female fatales in the future.
