It's a win-win for rugby league. One less Sydney team, one more "expansion" team, Cronulla fans can't logically be disenchanted with rugby league or the NRL because it wasn't their fault.
17,500 (all Sharks' fans )plus the numbers who could not make it suggest you are wrong.
If you believe they will not be disenchanted ,you are deluded.You know little about human nature and club tribalism.
Note what happened when Souths and Bears were punted,the fans hardly jumped en masse to other clubs,they were lost ATT.Some never to return in the case of the Bears.
Further ,there is another club according to Masters, that will be in a worse position than the Sharks.Remember 6 clubs.
