I disagree. If you make the decision to trade a talent of this upside, you better be getting a player back who is at least in their prime. If Hoffman pans out then Anthopolous will have traded two front-line starters for what amounted to be R.A. Dickey pitching at a #3-5 starter rate and the literal shell of Troy Tulowitzki with a half dozen years left on his massive contract. If prospects are currency, I'm not going to pay $50,000 for a Honda Civic and then pretend like it was a good move because my previous car was dying and unreliable. I also don't like the "well we got deep into the playoffs with Tulowitzki" argument because it implies that there were literally no other trade options available, which seems unlikely. Yes, Tulo was an important upgrade over Reyes, but he was still what, the 4th or 5th most valuable position player in the lineup on those playoff teams? Its not like he was carrying us in the playoffs.
