I can't speak to why BC hoops are on commercial radio, but I
can speak somewhat regarding the games being on WZBC, the non-commercial BC-owned station. Admittedly, it's been about six years since I was involved there (contract engineer), but WZBC
does provide live broadcast coverage of BC sports. Football, basketball, hockey and I think even some lacrosse. However, there are (or at least
were) some major differences between their broadcasts and the commercial radio broadcasts, for better or for worse:
- The sportscasters are all students. They tend to be a lot less polished than the professional guys, and they're also usually unabashed BC fans in the coverage. But on the other hand, they also tend to have a lot of passion, which is kinda nice. And in several cases, the sportscaster is friends or roommates with people on the team, so you get some great insider-knowledge tidbits.
- WZBC didn't use to have a good system for remote broadcasting; it was just a telephone-based POTS hybrid. I think it was an old Zercon Max-Z, actually. So the audio quality was gawdawful. Not just because it was telephone-grade, but also because the sportscasters routinely shouted so loudly that it distorted the line into an unintelligible mess (no compressor/limiter ahead of the mixer). I haven't listened in years, though, so they may have started using Skype and portable $50 Behringer mixers. It's more than a little Rube-Goldbergian but it can work pretty good considering how cheaply it can be done.
- WZBC has never had much luck getting stable underwriters, and BC Athletics goes out of their way to make it harder for any student group to monetize the games, so during breaks in the action the sportscast tends to sound really unprofessional as they struggle to fill the time. Used to be that during halftime the in-studio operator would just play music for 20 minutes. Ugh.
- Historically there has always been a tense relationship between WZBC sports and the longtime community DJ's who typically have the weekend shifts when a lot of sports games would pre-empt them. Couple that with a limited budget for travel and many years WZBC doesn't cover all the games; just home games...and often not even all the home games.
- Finally, and perhaps most importantly, WZBC is a music station. They take that mission pretty seriously. You wouldn't believe what an internal battle it was to get Democracy Now on the air. And to keep it, too...there were a lot of DJ's who wanted it gone after a one-year "trial run," despite how wildly popular it was and what a major earner it was during the every-two-years fund drive they run. (still run?) Anyways, sports is not congruent with that mission, and certainly listeners to the sportscasts are, by and large, not listeners to the regular music programming...and vice versa. For WZBC to be the primary source of radio coverage of BC sports would undoubtedly cause significant internal and external tension for the station.
Really, more than anything else, sports on WZBC is about providing an opportunity for BC students to learn how to be sportscasters. As long as that's the case, it means that WZBC isn't going to be suitable for a vehicle to deliver media coverage of BC sports to people who want to consume that media coverage. And the only way it would become suitable would cause too much disruption to WZBC operations
and remove most (if not all) of the opportunity for BC students to learn about sportscasting.
That was, if not "is", undoubtedly why you hear BC sports on commercial stations, too.
Interestingly, though, for a lot of college sports these days, having radio coverage is becoming near-totally moot. The best way to reach people who WANT to see/hear coverage of a college's sports is via the web; it's far more targeted and far more able to reach the parents and alums who frequently do not live within the local radio station's signal coverage area. And there are several excellent turnkey systems for sports on the web; we had one at Hobart & William Smith called "Sidearm" that was, I believe, created by Syracuse University. It was quite slick.
