Well, it helps to know what kind of league (h2h/roto/points) and what the categories are. It definitely does have effect how good your team is.
Overall impressions? You can't expect a better year out of an over the hill rodriguez while, in a 12 team league, there MAY be a couple catchers who were overlooked. Although they definitely should have been drafted, check to see if Barrett or more likely Martin might have gone undrafted. I also like Molina and Bard to have better years than IRod. You seem to be a little light on the power so I would probably go with Molina over Bard but that definitely isn't going to do much. If this is H2h.
I don't, almost as a rule, draft a closer until late. A lot of people do this and a lot don't. For me, there is just too many changes in closers every year to use a 6th rounder. nathan is a lock for good numbers, so, especially in roto, I can't hate on that decision too much.
