Such were the constant errors in terms of handling and decision making by the Crusaders, who were dressed in white, that they literally and figuratively appeared pale imitations of the side which has swept all Aussie teams before them since May, 2015.
"We were really desperate to play well and represent our people to show how much we care. You could see how hard we worked, but I think we dropped enough ball for the whole season so it's out of our system now," said Robertson afterwards, clearly pained at what he had seen but with sense of humour intact.
"It's a tough week, but we're Crusaders, we don't make excuses, we just needed to be better."
The Crusaders were poor defensively in the first half as the Waratahs shot to a 12-0 lead, and they missed the experience of resting All Blacks Richie Mo'unga and Scott Barrett and Owen Franks, a late withdrawal due to a shoulder problem.
Mo'unga's replacement Brett Cameron struggled under the combined pressures of the slippery ball and Waratahs' rush defence but there were few Crusaders who didn't contribute to their catalogue of handling errors.
"We were our own worst enemy at times," said captain Sam Whitelock. "When we went to exit we would drop the ball and give them another shot. There are only so many tackles you can make in a game. We gave them free goes at it and full credit to them, they took those opportunities and squeezed us on the scoreboard and we ran out of time at the end."
The Waratahs' kicking game was also far better, and in fullback Israel Folau they have probably the best aerial player in the world. "Foley and Phipps did a good job of turning us around the Folau should be working for NASA - I tell you what, he's pretty good in the air," said Robertson.
So, the Crusaders' record winning streak comes to a close, the clock re-set. But while there will be immense disappointment within the camp – more at the way they performed than the halting of a winning run – the setback could serve to allow them to re-focus on what's important.
Robertson said of the streak: "It was special and hence we wanted so desperately to keep that going… one good thing as you reflect is the way we won those games; from behind, from in front, finals footy. It was a great run and it's an opportunity to start again.
"One good thing about now is that we've got six days until we play again so we can have a great week as we look forward and really focus on the rugby."
