The Firebrand
At Arizona State, Paul Casey broke Phil Mickelson’s school single-season scoring average and Tiger Woods’ Pac-10 Championship scoring record. Since turning pro, he has made more headlines for his words than for his five worldwide wins.
Strengths: Power, great self-confidence
Weakness: A rare conversational frankness

The Technician
Luke Donald is arguably the best player in the world under 30, and already has won twice on the PGA Tour. With an even demeanor and a deadly iron game, Donald has the game to win majors.
Strengths: Ice-cool temperament, accuracy, course management
Weakness: Lack of distance

The Carouser
Nick Dougherty is the youngest of the six. He grew up playing the Faldo Junior Series, where the namesake star recognized Dougherty’s potential and became his mentor.
Strength: Consistency on the course
Weakness: Has he overcome the playboy lifestyle he liked a few years ago?

The Elder
David Howell’s late success makes him a relative newcomer into the top ranks of golf. His win over Woods last fall has helped propelled him atop the European Tour’s Order of Merit.
Strength: Wonderful putter
Weakness: Inexperience at the highest level

The Stylist
It’s hard not to recognize Ian Poulter, whether from his outrageous hair or his Technicolor wardrobe, of which Doug Sanders would be proud. Just remember: He has to be good to wear clothes like that.
Strength: Remarkable self-belief
Weakness: Does not hole enough putts

The Prodigy
Justin Rose has been around so long that it is hard to believe he will turn 27 at the end of July. But after several slow years, he is beginning to fulfill the promise he showed in finishing fourth at the 1998 Open as a 17-year-old.
Strength: Natural ability that took him to a high level when he was young
Weakness: May have happened too soon for him
