What can somebody with a marketing degree do for my company?

I am a partner in a company that runs adult websites and affiliate
programs.

We have a marketing team of 3 people. They were been hired because
they have experience in our industry even though none of them have
stepped foot inside a university or read anything about marketing.

I have spoken to one of the owners about hiring people with degrees
rather than the people we have. His response was, "Our business is
very different than what they teach in college, so there is no point
looking there."

I am writing to this newsgroup in hope of hearing a good response to
what he said. I would also like to create a list of what a person with
a marketing degree can do for our company that Joe Schmoe off the
street could not.

Thanks in advance for your responses.

Best Regards,
Felix
