they didn't say that the Mets would have to sign him first the feeling is there'd have to be a deal in place before MLB would make a ruling,and even that's just a rumor
it would be completely unfair to other ML teams for MLB and the Mets to make a behind the scenes signing and decision regarding the pick without announcing that they were PLANNING to make a decision..other teams without a protected pick who are waiting for his price to drop might act differently if they knew that Selig granted the Mets an exemption and would be serious suitors for Bourn
i don't think there's any MLB conspiracy going on here
