Welcome to the Cafe, MaggsIsMint - great name by the way!
I think you are absolutely correct to overvalue Rs and SBs. Id also put BA way up there too - this is roto, right?
I think you are on the right track in targeting those players, but if I were in your position, I would try and gamble with getting Pierre in the 3rd. If you miss out there are plenty of options that can be had throughout the draft: Pods is the obvious, theres Reyes, Figgins, Both Roberts can be had relatively late, Reed out in Sea is a late rd favorite of mine - Im sure you can come up with plenty of ways to get steals. The trick is to gamble - if you miss out on one, another value pick is a rd away - just dont jump for one - let one fall to you.
Eightan - picking Tejada over Beltran is bad, mkay.
