They seriously considered it with Giambi.
At any rate, they'd obviously love to be done with A-Roid. However, if they can't be, the last thing they want is to further alienate him. He's not a fan favorite. He can't be traded. I have no idea if he's well-received in the clubhouse but I doubt it. When you're a great player, your "quirks" are accepted. When you're not, you're just an *******.
I expect the Yanks to make an announcement that they stand behind him any day now.
