I wouldn't trust just yet Kaz but he's always had to tools to contribute fantasy-wise. He for sure isn't the future for Rookie SS with Tuly well on his way. Hopefully, the Rockies can sell high on Matsui with Tuly is ready.
A side note, I personally thought Barmes for Redman (pending FA) would have been the perfect deal to include in the KC/Col deal. It would have helped Colorado continue contend before they faded and Redman's GB ratio would seem to of fit in well at Coors. After Francis, Jennings, & I guess Kim Col has no stability in the rotation. Even the close to league min making Barmes would be an upgrade over Berroa. Barmes numbers actually aren't that bad, aside from his avg. His RBI's are quite good as far as SS go.
