How many touring professionals who're earning their livelihoods playing the game don't know their strengths and weaknesses? How many times has Jordan Spieth surmised that his incredible putting from outside of 5 feet has outperformed his often-times wayward tee game and helped him become the player on tour that he is today?
How many times did Dustin Johnson come oh-so-close to realizing his stardom, yet despite his prodigious length off the tee - recognized that his wedge game and putting were so average that he needed to devote more of his time working on his wedge play and putting?
Anyone think that Justin Rose doesn't recognize that his putting is ultimately the deciding factor with whether he's in contention, or simply trying to manage a top-10 finish on Sunday? How many times do you think Sergio Garcia needed a stat to let him know that despite being one of the best ball-strikers in the game throughout his career - that ultimately his putting essentially forced him to go 18 years before finally winning a major?
These guys who play at that level for their livelihoods are very much aware of which aspects of their games are strengths and weaknesses... which aspects carry them and which ones weigh them down when it comes to getting it done on Sundays. Rickie Fowler's played long enough to recognize that he doesn't need a stat to remind him that he's pretty much a world-beater on Thursdays, Fridays and Saturdays, and that he still somehow lacks the mental DNA to break through to win on Sunday in a major.
These guys don't need more stats, more algorithm feedback, or more miscellaneous number-crunching the aspects of their strengths and weaknesses to get them performing at their highest peak level. They're already well aware.
This strokes-gained stats stuff is nothing more that "experts" trying to let the viewers/fans know that they have a better understanding of why certain players excel and why other players struggle under the stress of either trying to make a weekend cut or winning on Sunday.
It's geek stuff. Except some of us who watch these players on a regular basis aren't geeks, and can clearly differentiate between the players with the complete game to win versus those who don't.
The only stat that matters is the 72-hole score after 4 rounds of tournament golf. These guys know they need to hit the ball long and straight, need to hit greens and make putts. They don't need a stat to tell them which areas they sucked at the prior four days come Monday morning.
Think Arnie, Jack or Tiger obsessed over stats back in their primes?
Let me answer that for you.
No.
