But that shouldn't drive the selection decisions.
There should be just two questions. What is best for the club, in terms of the 2016 NRL season? And what is the best way to ensure the Warriors - for a change - have a strong start to the season and are still there in September?
If the answer is Johnson, Tuivasa-Sheck and Luke getting early game time together at Eden Park, to work on combinations, fair enough.
But McFadden needs to be very careful with his decision.
Johnson shouldn't play. Hopefully it has been decided already - and just not made public - but there is no logical reason for him to be there.
Aside from the fact that helter-skelter games followed by abbreviated rest periods are not the ideal way to test out his ankle, the Nines are the perfect opportunity to give Jeff Robson time on the field.
The experienced Australian needs to build understanding and combinations with his new teammates and can lead the side through such a tournament.
It's also debatable whether Tuivasa-Sheck or Luke need to be involved.
Both went on the Kiwis tour and played their last match just 10 weeks ago.
And it's not just the physical aspect of the Nines, it's the mental demands of the weekend.
Look at how clubs like Melbourne, Souths, Manly and the Roosters have approached the tournament in the past two years. They have generally kept their most important players out of the action.
Unfortunately, it's not that simple. As tournament hosts, there is considerable internal and external pressure for the Warriors to do well and decisions about Johnson, Tuivasa-Sheck and Luke may be taken out of McFadden's hands. The trio will be keen to play and their presence could add a few thousand to the gate.
"There's no doubt there's more pressure on us in this tournament than anyone else," said McFadden.
"I don't know too many other clubs that would put too much attention on it.
"Obviously we do because of the circumstances. But I'm not going to put too much emphasis on it. I would like to do well [and] we will put out a strong side but it's not the be-all and end-all of our season."
