So the question is "Is it unethical to reveal another managers trade offer?" or is it a regular part of baseball just trying to get the best deal. If you are hesitant to get into a bidding war knowing someone else's deal just make your offer stand on its own. Of course just because you top the other deal doesn't mean he won't go back to the commish and say ok, you gotta beat this to him. I prefer to say something like I have a better offer w/o revealing names. I haven't read the unwritten-rules-for-ethical-fantasy-play book, but I'm not sure this really qualifies. At least he is being honest, even if it makes you a little uncomfortable.
