With Beltran, Rolen, and Wilson, I wouldn't say you have sub-par power. That being said, you did reach a bit for Wilson, but you stole Beckett in the fifth. Don't worry about starters for a few more picks. If there is a decent starting SS left, grab him now. Cabrerra or Fucal ideally, but they are probably gone. Don't reach if the SS pool is dry. Maybe grab a closer or fill out your outfield. If Huff or Sean Green (who should rebound this year) are available, grab one of them.
It's time to roll the dice.
