I believe this is the reason the UCLA radio broadcast of the game wasn't streamed. The only way one could hear it was to tune in to KABC 790 on your radio. From the NCAA website:
Westwood One has exclusive Internet streaming rights for every game throughout the
championship. Participating institutions and/or its radio rights-holder may not stream its
audio via the Internet. Violation of streaming policies could result in revocation of radio
rights. Participating institutions’ websites, as well as the website of an originating station,
may provide a link to the Westwood One Internet stream, which is located at
NCAA.com/media.
