Relocation wouldn’t affect the TV rights deal as broadcasters would still be getting their usual 8 games a week. If a franchise folded completely (if that’s what you’re alluding to) and we went back to the old system of 7 games a week + 1 team having a bye then yes I’m sure broadcasters would dispute this.
Re: Cronulla if they were to pack up shop and move to an expansion region (central Qld, Perth, Gosford etc.) they would lose say 10,000-20,000 supporters max? and it’s fair to say this figure won’t be changing anytime soon. Where as moving elsewhere could potentially see the Sharks gain tens of thousands of supporters so I don’t see any great value lost to the right’s deal through relocating them.
It’s the ‘elephant in the room’ in footy that there’s too many teams in Sydney and that rationalisation is needed to improve the game’s national standing. If the NRL (or ARL back then) could eradicate historic, foundation teams who’d experienced success such as the Bears and Jets then surely relatively young clubs with little success such as the Cronulla are expendable
