One man's trash can be another man's treasure. Even if the trash is a turd.
I had a player on one of my teams who was a regular position player. Not a star by any means, but filled a spot in my lineup until a prospect I was developing was ready. My prospect turned out to be ready a season earlier than I had expected, and the other guy was no longer needed. I posted him in the WC and was subjected to a couple of "turd" comments. But another owner found that my guy could fill a hole in his lineup, and he was able to trade a similarly no-longer-needed player on his roster to me to give me a slight upgrade at another spot on my roster.
A turd-for-turd trade, but we both got something we needed and benefitted slightly.
