Recognizing a common theme among most of the top players in golf today doesn't take a Ph.D. Dustin Johnson, Rory McIlroy and Jason Day are all hyper-athletic and launch the ball off the tee without any fear. Based on that, our prediction is that Brooks Koepka is next in line for stardom.The huge-hitting Floridian has won seven times on tour. And he's poised for more hardware. "The way the modern game is played and given his attitude—nothing fazes him—Brooks has what it takes," says Claude Harmon III, who has worked with Koepka since 2012. "He's become a really good driver of the ball, and he's added more shots. His putting has improved a lot, too. It's a complete game."Koepka has geared his swing to produce a "pull cut," his coach says. It's a shot that starts left but gently curves back toward the target. And with clubhead speed reaching 128 miles per hour, Koepka routinely carries it 300-plus yards. "He hits a very heavy ball, like a boxer who throws hard punches," Harmon says. "It's a great swing to copy." Though your mileage may vary. – Matthew Rudy
