The captain's challenge may have been used for the first time at Saturday's All Stars clash but rival skippers agreed they were no closer to deciding whether it should be introduced to the NRL in 2020.
Maori co-captain Adam Blair created history when he used the on trial rule in the 65th minute of their 30-16 victory over the Indigenous All Stars to question a knock on against Kenny Bromwich but was unsuccessful.
The challenge is also being trialled in next weekend's Charity Shield clash before a decision will be made on whether to adopt it for the 2020 season.
"We had 15 minutes to go, we hadn't used it and one of the boys said 'captain's challenge'," Blair said.
"I didn't see what had happened but Kenny said it was a rake so I was like whatever, give it a go," Blair said.
"Lucky it didn't come back to hurt us."
But Blair admitted he wasn't sure what to make of the challenge concept.
Under the proposed rule, the on-field captain is permitted to challenge a referee's decision but has just 10 seconds to make up his mind and can only implement it during a stop in play after the whistleblower's call.
If they roll the dice and the challenge is unsuccessful, they don't get another chance to use the option in the game.
But if the bunker review gives the captain the green light, he can use the challenge again and again until he strikes out.
"To be honest unless it is blatantly obvious and something they have missed, it would be good for those times," Blair said.
"(But) you are putting a lot of trust in your players if you are the captain because you don't have time to look up at the (big) screen (for replay).
"Whether that works or not we will see how they go."
Maori coach David Kidwell agreed with Blair's concerns.
"If it happens on the wing and the captain is on the other side of the field and hasn't seen it, it could be costly," he said.
At least the Maori got the chance to use it.
Indigenous captain Joel Thompson claimed he tried to use it during the game but the referee didn't hear him.
"I tried to use it. I was yelling at the referee but he wouldn't even listen to me, (but) all good," he said.
"It is something players need to work on and be more aware of. I have been playing footy for so long and never heard of it before, it's a new thing so we will see how it goes at the Charity Shield."
