Ever since Rory McIlroy won the Open Championship last July, talk of the 'Rory Slam' has been a constant in the ever moving world of golf.
With one US Open, one Open and two USPGA titles now in the locker, Rory can join an elite group to have won all four of the sport's majors if he can do what many feel he's certain to one day - win a Green Jacket.
The task is a massive one. McIlroy has spoken of how this is the most challenging event of the year from a mental perspective, and while he's well versed in dealing with hype there will be new levels of it this time, particularly if Tiger Woods is not present.
That's without considering the fact that the opposition - with or without Woods - is outstanding. The theme of the weeks and months leading up to the season's first major has been that the biggest threats to this storyline have demonstrated that they're in top form.
And then there's the course. So far, a best of eighth in six visits suggests that McIlroy has much to learn about the intricacies of Augusta National although clearly, he did alright for 54 holes back in 2011. That he's been back to gather more knowledge alongside course professional Jeff Knox can only be a positive, but the fact remains he has not yet finished inside the top five after 72 holes.
Tee-to-green there are no issues. Rory ranked second for greens hit in last year's Masters and third in 2011, while in three of his last four visits he's been in the top quarter when it comes to driving accuracy as well as distance. His preferred shot - the booming high draw - is perfect from the tee here and there's no finer approach-shot exponent in the game.
The problems come on and around the greens. Only once in his last four visits has McIlroy scrambled successfully more times than not, while he's yet to finish inside the top 10 for putting. Had McIlroy played enough rounds to figure in the PGA Tour's 2015 scrambling stats, he'd be way down at around 180th, so if he doesn't win this event the likelihood is that it'll have been his short game which costs him.
Compare his overall course record to challengers Jason Day, Bubba Watson and Jordan Spieth, who are nothing if not Augusta specialists, then factor in those short-game concerns, and there are plenty of reasons to doubt that this grand slam is going to happen this year even if most of us think he will surely win the Masters one day.
Then again, McIlroy is the most outstanding golfer on the planet. His best is the best - and by a few shots, too. He's won four majors while Day, Spieth and Dustin Johnson still seek their first. He just might do it.
