Matt Holiday DOES intrigue me. OK power OF in CO could always have something happen. I like Mike Gonzalez a lot too though so the deal is kind of a toss up. I don't see Williams contributing a lot this year. I'm not sure I would have quite given up so much for him but, as these are kind of scrubs, it's more a case of what you think they might do for you.
I'd rank them: Gonz, Holliday and Williams w/ Gonz the highest so I'm not sure I'd go for the deal BUT, if your P are fine and you are looking for an OF w/ some upside, that's an ok deal. BP points out that Holliday played quite above what he'd project at based on his minor league numbers but he is 25 so he could end up either way.
