This one is going to be real close I think. I have Rios, Ichiro, and Granderson lumped very close together.
My vote here is for Ichiro. Though I recently read that pitching hurt his shoulder, which I am ignoring for the purposes of this vote.
Ichiro is not going to produce the HR and RBI of the other two, but neither have proven to be serious power sources nor RBI sources. Ichiro should more than make up for his deficiencies in those 2 categories with a significant advantage in SB and AVG.
If I believed that Granderson was going to steal 26 bases again like in 2007 (he only had 12 in 2008), or if I believed that Rios would repeat his 32 SB season of last year (he had 15, 14, 15, 17 in his 4 previous seasons), then I'd lean toward those 2 over Ichiro. But I don't believe either will steal more than 20 bases, Granderson might not steal more than 15.
i'm the guy that puts the "nip" in omnipotent...
