— -- There was once a time not too long ago that we measured greatness in golf against the otherworldly accomplishments of Tiger Woods.

Rory McIlroy is a long way from Tiger's 79 wins, including 14 major championships. But all signs indicate that after his victory at Valhalla, his second consecutive major win, McIlroy is on his way to setting his own bar for excellence in the sport.

Other notables on my board -- Phil Mickelson, Rickie Fowler, Henrik Stenson, Jim Furyk -- were great this week at Valhalla. But McIlroy was just too good. His grasp on greatness could shape the next 20 years in the sport.

With his remarkable play, Mickelson reminded us of the past. But McIlroy and Fowler showed us on Sunday that the game must push forward with new superstars who will inspire us to support great, compelling pro golf, no matter who is playing it.
