I'm debating on what I could use help with in my minor league system. Talked a little bit about my system here, and was wondering where the biggest hole I should be working on.

Major League Roster:

C: Geovany Soto
1B: Derrek Lee, Todd Helton, Jake Fox
2B: Ian Desmond (SS), Eric Young Jr.
3B: Chipper Jones, Brandon Wood
SS: Ryan Theriot
OF(3): Nate McLouth, Julio Borbon, Michael Brantley, Nyjer Morgan, Adam Lind

SP: Rich Harden, Mat Latos, Luke Hochevar, Ricky Romero, Wandy Rodriguez, Vin Mazzaro, Marc Rzepcynski
RP: Daniel Bard, Chad Qualls, Jeff Samardzija

Minors:

C: Buster Posey, Carlos Santana
1B: Justin Smoak
3B: Josh Vitters, Neil Walker
SS: Carlos Triunfel, Grant Green
P: Tim Alderson, Martin Perez

Clearly, I've been rebuilding, but I am wondering if there's any position I should be targeting, or honestly just looking for who I think the best player available is. I'm probably at least another season away from competing in this league, but always looking for suggestions. Any help is greatly appreciated.
