Tiger's a lock.
Kim -- if healthy (a big if) --is probably in as well.
I like Z. Johnson; he performed fairly well in '06, single-handidly winning a four-ball match against Harrington and Co. in front of a very tough crowd. A very good putter, and I'd think a solid foursomes pick (unlike Tiger, who I wouldn't put anywhere near a foursome match).
I think Cink (now 14th in points) has a very good chance to get picked; he's played in several of these, and one of few guys under consideration who was a true playing colleague of Pavin, which has to help his chances.
My crazy wild-card pick is Fowler (20th in points), who seems to have that cock-sure, go-for-broke attitude that comes in handy at the RC.
