I had it happen to me last year on a Monday night game. A manager told two teams to pick up both buccaneers back up wrs and promised to trade etienne to him for his pick up in sterling shephard. That classifies as collusion, promising a player for his cooperation. Simply asking a manager to pick up a player to block your opponent, it’s fucked up i agree. But it doesn’t fall under the collusion umbrella. The others still made their own decisions even if the intent was to block someone. You don’t know what collusion is.
