The Crusaders' 28-0 unbeaten home playoff record is one that would strike fear into any opponent.
But Friday night's Super Rugby Pacific semi-final against the Blues poses arguably the biggest threat yet to their perfect record.
The defending champions have been plagued by injuries this season and will be without eight All Blacks for their biggest match of the season.
Of all of Scott Robertson's Crusaders campaigns this one has come with the biggest challenges.
"We play a tough game," he said. "It's a physical game, people are going to get injuries.
"They're going to come."
And they have, in droves. Forcing them to field a whopping 48 players this campaign.
The Crusaders themselves don't want to start making excuses, but it would be easy to in a season that's felt like death, taxes and injuries.
It all began in round one against the Chiefs when prop Fletcher Newell was ruled out of the season with a toe injury.
Next was winger Sevu Reece as a knee injury ended his World Cup hopes. Two weeks, later prop George Bower suffered the same fate in a clash with the Reds.
In May, a third All Blacks prop went down, this time Joe Moody being ruled out of the rest of the season with a troublesome ankle.
That same month, David Havili's season was over with a hamstring issue as Cullen Grace dislocated his kneecap in the same game against the Waratahs.
Then last week Ethan Blackadder's return lasted just four minutes before a quad strain ended his campaign.
Adding to it all, arguably the lifeblood of the Crusaders, Sam Whitelock is yet to recover from an Achilles issue.
Of the 15 All Blacks in the Crusaders squad more than half are injured. That may be just the advantage the Blues need.
"What an opportunity for us to go down there and beat the best," said captain Dalton Papali'i.
"You don't want the easy path, you want the hard path."
But despite an injury ward overflowing with All Blacks, the Crusaders are backing themselves to find a way.
"Putting teams under pressure, that's what we sort of hang our hat on," said Crusaders captain Scott Barrett.
"How we do that? We won't reveal too many secrets."
You'd be brave to bet against them extending the unbeaten home record to 29.
