Not living there, but I wonder, assuming the answer is "no" here----
Has any major sports team (NFL, NBA, NHL, MLB) ever been so bad, or at least unprofitable in radio station owners' eyes, that no games were broadcast on the radio? That is, was there no network or flagship for the team---at least since radio became a major force in the 1940s/50s?
The closest I know is the lack of an English network for the Montreal Expos in 2000 I think Wikipedia said, and all the games could only be heard online. I listened to one of the "goodbyes" after one of the games.....creepy!
