Here are my 5 against the field, picking them on previous USPGA form, not necessarily on current form.
Ernie Els 3 top 10's in last 5 years, 16th in other and missed a year through injury trading @ 30
Adam Scott, 2 top 10's in last 4 years and 12th last year. Trading @ 38.
Geoff Ogilvy, top 10 last 3 years trading @ 44
KJ Choi again, top 10 twice last 4 years and 12th last year. Trading @ 50.
Woody Austin, 2nd last year and made the cut previous 5 years. Trading @ 210
Good luck all
