Your projections for Kaz are too tough on him, but if Uribe gets playing time then he might be a better option than Kaz. And Uribe's defense actually does help in fantasy. It gets him in the lineup more than if he was bad defensively. I think the Sox want Harris playing 2B everyday, and they also seem partial to Valentin, so I don't know how they're going to get those 3 in the lineup every day.
