No, he's about the same as Williams. I like Guzman, but he hasn't done it in the majors yet and is injury prone. I don't count on Prior to make over 30 starts a year, so I think we need to anticipate him being on the DL for 25-50% of the season. That alone will give young guys a lot of opportunity. I'd like the top three to be filled by at least above average pitchers who typically make all of their starts. I would wait until the end of the year to assess wood, prior and miller. At that point you might have a better read on williams, marshall, guzman, hill, and ryu as well and know better what you need. I wouldn't trade for Zito under any circumstances (barring a give away of course).
