As I said over on the other board, It's just the media relations guy trying to do something extra for the fans. They'll have a regular radio guy once SEC play starts.
You need to understand that this isn't all he's doing. While broadcasting these games, he is also scoring the game using the computer stats program that isn't always easy to navigate, checking stats, live-tweeting the game and doing the live blog.
Adding this to his plate was something UT did as a low-cost measure just to add an extra thing for the fans. Once they're done with preseason tournaments, the regular sponsored radio/internet broadcast schedule will begin with Mickey Dearstone or whoever fills in for him during basketball conflicts. If you want to complain about those, you'll be well within your rights, as someone will be there specifically to broadcast.
Certainly UT would prefer to send a broadcaster to these early tournaments, but it's very expensive to do so and no one has stepped up to pick up the tab. It's also risky because not all of these locations have the internet or phone lines at each field necessary to do a broadcast. Using a mobile broadband card works, but can be spotty, and you can't have spotty when sponsors are paying for it.
