This type of thinking is a big reason why Adam Dunn still does not have a long term contract. You have to have the foresight to lock up your players before they price themselves out of your market.
Exactly. If he slumps, and you think 05 was a flash in the pan and want to unload him, there will likely still be suitors out there who will think Felipe can return to 05 form.
This team needs to step up and set a course for the medium term, not just by adding pitching, but by investing in a core of young offensive players (I'd start with Dunn and Felipe, and then consider Kearns or Pena). It's called executing a plan.
