Now that Jason Day is officially the best golfer on the planet, it's time to ask, can he become the best Australian golfer of all time?
It is standard practice for us in the media to play this card - when someone becomes great, it is our first reflex to turn them into "the greatest". It is not enough for our heroes just to win, we demand they keep winning.
But where Day is concerned, it is not unfair to heap that type of pressure on his broad shoulders, for several reasons. 
First, he has time to build a career to match those of the legends.
At 27, he is the youngest world No.1 Australia has ever produced, eclipsing the mark set by Greg Norman when he became golf's leading man at age 31. Second, he not only understands this expectation, he thrives on it. He runs towards it. It is his personality to be a winner.
Speaking after his latest runaway, six-shot victory at the BMW Championship on Monday, Day gave an insight into the mindset that is driving him to greatness.
"All I want to do is win, and that's kind of been the mentality," he said.
"Ever since the Open championship [in   July] something changed in my head. I felt like it was my time to start winning tournaments and ever since then it has just been a phenomenal run."
By becoming world No.1 on Monday, the Queenslander has fulfilled a goal he has had since he was a teenager, when he said he wanted to dethrone Tiger Woods. Now that he has, there is plenty of time for him to become Australia's GOAT (greatest of all time). How do we measure it?
Is it about winning majors? If so, the figure to chase is Peter Thomson, the Australian who won five Open championships between 1954 and 1965. Or is it just about winning more tournaments on the PGA Tour than anyone else?
On that score, it is Norman whose footsteps he must follow. "The Shark" won 20 titles on the world's biggest tour. Day has now won seven but is climbing that list with a rocket.
Or is it just about playing well enough for long enough to spend more weeks as world No.1 than anyone else?
Again, Norman is the king of staying on top of that mountain, having done so for 331 weeks over 11 different stints in his decorated career.
On any score Day has a long way to go. But this year is proof of how far one can go in a short space when when a golfer enters the zone.
It is hard to win events on the PGA Tour, especially FedEx Cup "Play-off" events like the BMW Championship and The Barclays, not to mention major titles like the PGA Championship.
But you wouldn't know it watching Day over the past few months, as he has won four out of his past six tournaments. His past two wins have been the kind of dominant displays that make the final round a mere formality. That is Tiger Woods stuff.
Day has had the most birdies and fewest bogeys in a single season since Woods in 2009. That gives an indication of the remarkable consistency that has underpinned this rise to the top. And it holds him in good stead to stay there.
As hot as Day is now, Jordan Spieth was even hotter earlier this year. Who would have thought he would not end this year as world No.1? And before Spieth really caught fire, it seemed like Rory McIlroy was ready to take over the sport in the same way as Woods.
