Robertson - who broke out his trademark break-dancing routine on the Ellis Park turf after the match - said that blot on their copybook was now rectified.
"A Sam Whitelock, a Joe Moody, a Matt Todd, a Luke Romano - all of them, those guys, they've created a bit of history for themselves," Robertson told reporters.
"Now, on their CVs, they can say they've won it (and) can say they've added to the esteemed history of the Crusaders jersey.
"Because we had so many All Blacks who hadn't won it, I did play on it a bit."
In what was the Cantabrians' first Super Rugby triumph since 2008 and their eighth overall, Robertson's troops achieved a competition first - they crossed the Indian Ocean for the final and emerged victorious.
Yet they struggled at times on a dry track, with their arduous travel commitments and the 1750m altitude taking a toll.
Tamanivalu went over in the ninth minute, sprinting 80 metres to the tryline after some shoddy Lions breakdown work, before Goodhue crashed over in the left corner two minutes later.
Smith's red card then left the Lions with too much of a second-half mountain to climb, with coach Johan Ackermann off to Gloucester on a sour note.
Robertson, meanwhile, became the first person in history to lift the Super Rugby trophy as both player and coach.
"Even with 14 men, our boys were shattered with 20 to go. It's like we needed 12 on the bench," Robertson said.
"I just kept sending messages, you've got to be strong with your body language, you have to just break it down into two-minute blocks.
"The players' effort was just phenomenal."
