It looks like Posey may be a great pick for most unless you plan on doing the AL Collection soon as I don't think there will be too many catchers better than Craig Biggio or Buster Posey very early on considering we got the Ivan Rodriguez in the Evolution pack and Mike Piazza as the Dodgers collection reward.
I would consider Reggie Jackson in your situation as you have the consensus "elite" options at 1B, 2B, 3B, and SS.
