I think the only hope of RC fired at this point is if nobody shows up at the home games. Yeah, there's the already paid ticket holders, but loss of other revenue and the embarrassment of an empty arena may finally start getting to Samueli to do something. Of course, we all know that half our attendance if for the other teams, so that's going to be tough to accomplish.
Regardless of the tanking opinions, I think you still get rid of the cancer in the room. It can only spread and get worse... and the longer it goes on, the tougher it is to heal.
