I am fairly certain they would take Coulter, Arcia, and Taylor for Tulo. I doubt any team would be crazy enough to top that. I think you are greatly underestimating the value of Tulowitzki. You are talking about arguably the best player in baseball at a premium position. These are nice prospects, but very raw, and therefore still much less of a sure thing than a top AAA prospect who has blown through the minors. There's not even a top 100 (as of the last ranking) prospect among them. I would be willing to bet if there were a Tulo sweepstakes, numerous teams could and would top that. I would bet that if Tulo for Coulter, Arcia, and Taylor was an option for us, Doug would pull the trigger within about 2 seconds before they could change their mind.
