Koepka established himself as perhaps the best major golfer in the world last season. All of this after he started the season on the DL with a wrist injury as well. That injury limited Koepka to just 17 events last season, but he still managed to win twice and post a career-high in earnings. Koepka has won three of the past six majors, five of which he has played and it's clear that when he's focused, he's one of the best, if not the best, golfer in the world. There in lies the issue though as Koepka all but admitted after his PGA Championship victory that he gets up for majors and struggles to do the same during regular PGA Tour events. It's hard to imagine that Koepka won't figure that part out soon and if he does, then the sky is the limit. Koepka comes with a huge price tag this season, but he does have the potential to reach $10 million if everything goes right.
