Short-priced favourites to claim a third title on Saturday and a 10th in total, the Crusaders are wary of the sort of passion the underdog South Americans will bring to their maiden appearance in the decider.
While the Crusaders are renowned for their methodical, almost tunnel-vision approach, flanker Matt Todd said the looming last game for a number of acclaimed teammates will play a part this week.
Japan-bound All Blacks captain Kieran Read is the longest-serving departee, having debuted in 2007.
Midfield back Ryan Crotty, prop Owen Franks and flanker Jordan Taufua have all notched a century of games in red and black while Todd himself has yet to commit to next season.
Captain Sam Whitelock is also taking next year off under a sabbatical in his NZ Rugby contract but will return in 2021.
Last year's side didn't have the same post-season clean out although players admitted they had been inspired to win for retiring prop Wyatt Crockett, the most capped player in Super Rugby.
Todd said sadness enveloped the team on Tuesday when Crotty was ruled out of the final with a fractured thumb suffered in last week's 30-26 semi-final win over the Hurricanes.
"You're gutted for him. It was his last game for us and he's a massive part of the Crusaders. And I know how much the Crusaders mean to him," Todd said.
"You hurt for him but he's still around the team and as positive as ever so that will be on our minds through the week."
Crotty and fellow-All Black Scott Barrett (broken finger) have been replaced newly selected All Blacks back Braydon Ennor and lock Mitchell Dunshea respectively in the only changes to the starting team.
Ennor will start at outside centre, pushing Jack Goodhue in one spot.
Todd expected the newcomers to step in seamlessly.
"You can't replace world class players just like that," he said.
"But we trust the whole squad. Everyone's had opportunities this year and they've performed so I guess you plan for that all year."
