I personally feel that pro golf is coming close to reaching a new golden age. While I could appreciate the brilliance of Tiger and Phil Mickelson, the lack of sustained competition from other top players at that time always felt hollow to me. These days we have numerous world class players with incredible golf games who are vying for the No. 1 ranking in golf such as Dustin Johnson, Jason Day, Jordan Spieth, Rory McIlroy and Hideki Matsuyama.
The only potential negative issue is that some players may get overrated and overhyped despite not actually deserving it. One could make a case for the 22-year-old Jon Rahm as the young player that is overhyped because he has yet to win a major. However, I think a look at his metrics show that he’s on a path to being worthy of being mentioned among the names I listed above.
Rahm is currently ranked 25th in the world and is only 22 years old. I wanted to compare his metrics thus far versus the metrics of Jordan Spieth’s 2015 season when Spieth turned 23 years old, won more than $12 million and also claimed a Green Jacket and a U.S. Open victory.
I adjusted the metrics above to more accurately represent both player’s skill. For example, if two players each hit 60 percent of their fairways for the year that may appear that they are equals in terms of tee shot accuracy. However, if Player A played courses where the field average hit fairway percentage was 50 percent and Player B played courses where the average was 70 percent; Player A was actually far more accurate than Player B off the tee.
Therefore, Rahm is driving the ball more effectively than Spieth was in 2015, but the margin is narrow. Rahm hits the ball much farther due to generating superior ball speed and having more of an upward attack angle with his driver. They are roughly the same in terms of accuracy and precision as well as their percentages of laying-up off the tee.
Spieth was clearly better from the Green Zone (75-125 yards) than Rahm is now. However, having examined Green Zone performance from a mathematical standpoint we see that Green Zone doesn’t mean very much in terms of success on Tour. As we see with Rahm, who is one of the worst on Tour from the Green Zone, he’s had a very successful season thus far.
Rahm has the advantage in the Yellow Zone, but Spieth was certainly not poor from the Yellow Zone. And from the most important zone (Red Zone), they are virtually equals in terms of performance.
Overall, I would give the slight nod to Spieth in 2015 over Rahm this season for approach shots. Just like I gave Rahm the slight nod to Rahm over Spieth in Driving.
Spieth was clearly superior in his Short Game compared to Rahm this season. However, Rahm is still a very good Short Game performer. In fact, he was a superior bunker player, but Spieth’s ability from the greenside rough was phenomenal and made him one of the very best Short Game performers in 2015.
Spieth in 2015 was clearly the better putter overall. Where Spieth separates himself from Rahm (and the rest of the planet) is his ability to make putts from 15-25 feet. In the end, Rahm is still a pretty good putter of the ball.
This doesn’t mean that I think Rahm will have a season like Spieth’s 2015 season. The bigger difference between the two is that Spieth was into his third season as a professional in 2015 while Rahm is still a rookie. And in the end if a golfer “just falls short” of Spieth’s performance in 2015, they are still going to have an incredible season.
What the metrics do indicate is that Rahm is set to have an incredible season and given his lack of experience, I would expect him to start contending for the No. 1 player in the world very soon.
