Rory McIlroy is the top-ranked golfer in the world and there's no reason to think he won't continue to play stellar golf and add to his victory and major championship total in 2013.
Tiger Woods is coming off a solid year in which he was the No. 2 money winner on the tour behind McIlroy and he also won three tournaments.
Woods did not win any majors and had some flaws when it came to finishing tournaments on Saturdays and Sundays, but he played with the hunger and desire that golf fans expect to see from him.
He's not going away any time soon.
However, the PGA tour is filled with golfers who can challenge McIlroy and Woods. Here's a look at five who could make a run at the top spot.
