I'm new to this site (more of a Steelers fan), but I grew up watching the Pirates.  I've been reading the site for a few weeks, and I've seen a number of people saying something like "we still need more pieces", and questioning whether the Pirates could contend with their roster.  I confess I'm not a baseball expert and most of my knowledge of the Pirates comes from stats, but when I look at this roster, I see a ridiculously young team with a bunch of ~.300 hitters and a number of very young pitchers who have at least shown that they are capable of a 3.5 to 4.0 ERA.  Obviously Gorzelanny and Snell are crapping their pants this year, but they have 5 SP's and a closer under the age of 27.  Is it possible that Snell and Gorzo return to form?  I don't know enough about how baseball players develop, but is it unreasonable to expect that in a few years the Pirates will have a strong rotation to go with their solid lineup?

I could understand trading Marte, Nady, and maybe even Bay while their stocks are up, but do the Pirates need more than a little more depth?
