Here is an example of trade advice from the thread "The Art of the Trade"
"It's simple: find the most injury riddled, pathetic teams that are now 0-2 and in panic mode rt now and dangle your depth players in front of them for one of his studs. If the owner had forte and/or fjax he is likely on life support rt now and starting a guy like Dwyer. If you are deep at rb you guys are perfect trade partners. Sart by offering him multiple rbs (your rbs 4 and 5 for instance...like a Hillis and a Ben Tate for example) for his most studly wr or whatever area of need you have. You'd be surprised what a desperate owner will do to shake up his team after a very bad start to the season. If he doesn't go for that tell him your stud rbs are available and don't be afraid to trade one awAy if you have depth as long as you are gettin back a kings random for him. And b that I mean any combo of 2 stud wrs, qb/wr, TE/wr etc. For a legit stud rb you might be able to score jimmy graham AND a high end wr2 from a desperate owner. Again if ur deep at rb you won't miss a beat and will gain at 2 valuable positions. "
So when somebody actually follows this mostly terrible, predatory advice, and luck of the Irish, is actually successful, they then get to look forward to emails about collusion and getting kicked out of the league.
In week 3, its just being a ####. In week 11, you're trying to get away with something.
Likely, but I still think the trade is more temper tantrum than motivated by anything else. The lack of other contextual details that have been asked and not answered from the poster still leaves a shadow of doubt though.
While this trade is lopsided, I still think the league mates simply have their own best interest in mind and not the interest of the league at heart. I simply contend that any trade that negatively impacts many teams chances will always find a way to be scrutinized as "collusion".
I was in a league where I was accused of it once. I traded a "stud RB" for a backup RB. The thing is, I offered the same player to the accuser originally. He declined all offers. I then offered to auction the RB off to the entire league, no bids nothing. Then finally I made the only deal I could, then and only then, did anyone #####. And they #####ed simply because my team was in win now mode and the other guy was in a comfy spot.
The point? Context is pretty important, and simply trade "balance" is not evidence enough if collusion but complaining about an unfair trade is evidence of sour grapes.
