My understanding is that the other (minor) creditors would get more cash in the Onion offer because the Sandy hook reps weren’t going to take their huge cut in the event their preferred bid was accepted. That means in any other deal, the other creditors would be strictly worse off. The families would be financially worse off but they were the ones driving the decision, so they clearly felt holistically better off.

I don’t see how they shouldn’t be able to take less money themselves as long as the other creditors also got more money.
