"No matter how good you are, you're going to be up against it."
Helping out the team against the Saracens, Wanganui legend Peter Rowe went to question referee Rebecca Mahony after the match about her interpretations and accepted the former Black Fern's explanation of her decisions.
But Rowe is no longer on the field and Caskey expects his current players to understand if they get pinged once, it is insanity to do the same thing and expect a different outcome.
He would rather they just leave the ruck ball alone and get back on the defensive line if they can't get on the same page as the official.
"Whether you think it's right or wrong, they've got the whistle. It's stupid if you don't start changing to suit.
"If we haven't, there might be some serious questions asked of the players."
Caskey would not be drawn on whether Madams, who dominated the semifinal in Timaru but whose alleged sledging upset Matthews and his players so much that he was ultimately ousted from the Heartland squad, was determined to be the best player on the park tomorrow.
Both sides would be up for a big match to set the Heartland campaign off right, with the Cantabrians still trying to find the magic formula to win the Meads Cup after falling in the playoffs for the past three years.
"These things you carry in you and they remember it," said Caskey.
"Most people are going to have motivation, being it's South Canterbury.
"We got plenty of motivation to start the season well, get to try and make advantage of that home ground.
"Five [points] is an absolute bonus, especially against teams of strength. You'd be happy with four and then just run."
Both teams have tough first halves to their Heartland draw, with Wanganui having the better side of the coin in that they at least get to face South and Mid Canterbury at home, whereas Matthew's squad has to go on the road to play the Butcher's Boys and last year's Meads Cup finalist Horowhenua Kapiti.
However, having secured a handful of loan players – five named in July – Matthews told his local paper they have more depth and stronger forwards.
Prop Kalolo Otutaha, loose forward Matt Etheredge, and centre Henry Scott have been spotlighted as dangermen, while Canterbury standout Dan Dorgan, admittedly the son and great nephew of South Canterbury legends, is coming back from injury and Canadian lock Reegan O'Gorman is also on the roster.
It is notable that as a union, South Canterbury should be able to call upon a local player base comparable to Wanganui, given they have a nine club top grade and eight teams in Senior B.
Remembering the semifinal where Matthews was looking to bring back some imports who had been injured or away from the team, replacing guys who had been winning every week, Caskey pointed out an outsider-stacked side does not necessarily a winning recipe make.
"If there is a need, if you've got a shortage [do it], but that team culture is massive and if you start chipping away at that..."
Wanganui struggled with injuries before Timaru, but the team christened themselves "the Battler Boys" and went together to claim the win, with only one imported player, then expat Tom Stewart, on their bench.
Injuries are still the bane of Wanganui's existence as right when second-five Penijamini Nabainivalu is ready to come back, centre partner Kaveni Dabenaise could not train on Tuesday, with Kameli Kuruyabaki on standby to start.
In addition, fullback Craig Clare did train some of Tuesday night, but will still have to get through a Saturday morning fitness test satisfactorily.
Shandon Scott is his standby, with young utility backs Ethan Robinson and Tyler Rogers-Holden ready to cover the bench.
"We took [Clare] out later because he was tightening up a little bit," said Caskey.
In addition, prop Viki Tofa has been on contract work over in Waipukurau and while he has trained at least once a week in preseason, he could not make it back for either Tuesday or last night, with Gabriel Hakaraia promoted to start and pack down with Dylan Gallien, now the preferred hooker.
Despite the loss to Tofa, Caskey has complete confidence in Hakaraia, Gallien, Kamipeli Latu and reserve Wiremu Cottrell to cover his absence.
"It's hard to put him in when we can't get to training.
"Kamipeli has been there as part of the team as many years as Viki, apart from when he was overseas.
"It's Gabe's second year, he should know enough."
Kickoff will be at 2.30pm, following on from the Wanganui Toyota Development XV playing the curtain-raiser at 12.30pm.
