nice team for a 12-teamer.
your hitting could use some extra bags, but not many. Roberts and Wright will keep you afloat there. of the names you mentioned, i think chipper might be the only person who can net you enough quality in that area. there is usually someone who is lacking at 3b in a 12 team league...
as is always the case with young pitchers, there is upside and downside. with the names you have, i think the upside far outweighs the downside. depending on how they do, you may need to pick up another consistent pitcher a la Meche 00
good luck to you
