In any trade the team that got "the guy", in this case Alomar, gave up more than all the other teams that were interested. Did we give up 150% more? 100% more? 25% more? I'm betting our offer was just about the same but the Mets might have tried to:
accomodate a future HoF,
moved him from the NL,
dealt him to a contender.
I'm a little worried at how happy Met's fans are to see him go. He may have been the poster child for the team's lack of success.
