People who manage that way are seat warmers. They will never win a championship. People who know their rosters and have a plan or goal in mind win championships.
Nobody forced you to bid. You best have a plan and know what you are doing... Not you specifically, anyone. This isnt a fly by the seat of your pants journey.
If you then place five more bids... They are all illegal until that illegal bid has been removed. When i remove an illegal bid. Everything after it is also removed. Cant make a legal bid with an illegal roster or bid on the board.
The fact someone posts PC. Even if they have an open minors spot. If the bid is illegal because the player doesn't qualify for PC... Its still illegal. The roster spot is only one requirement.
