Even if it was Endy, he's still getting a good deal. Marcus Giles is worth more than Izzy, and Castilla doesn't change much. There are tons of better 3B's.
If it was Eric Chavez and Marcus Giles for Izzy and Castilla, then I would certainly hope your league would veto the deal. That's just ridiculous.
