Using one from each year '97-'05, and assuming death does not hinder ones ability to play, here goes:

Stu Ungar (1st '97)
Scotty Nguyen (1st '98)
Erik Siedel (4th '99)
T.J. Cloutier (2nd '00)
Phil Hellmuth (5th '01)
Minh Ly (9th '02)
Dan Harrington (3rd '03)
Greg Raymer (1st '04)
Mike Matusow (9th '05)

I could also throw out Huck Seed (6th '99), Chris 'Jesus' Ferguson (1st '00), Carlos Mortensen (1st '01), and many others.
