I ask this question because people say that if tanking isn't against the rules, then it's fair game, but what about collusion? I'll give some examples below.
Scenario 1: Team A trades players to Team B and they agree to split any earnings
Scenario 2: Team C trades star players to Team D, but it is for what the league has determined as fair-market value. There is no agreement to split earnings, but Team C wants to trade to Team D because he dislikes the other owners in the league and wants to make things tougher for them.
Scenario 3: Team E agrees to not enter into trade talks that Team F is involved in, because Teams E and F have a close personal bond. Likewise, Team F agrees to not enter into trade talks if Team E is involved, but Team G wants to hear bids from all interested teams.
Scenario 4: Team H agrees to trade a certain package of draft picks to Team I, if Team I beats Team H in their matchup that week. The trade would still be for fair-market-value though. Also assume that teams have been able to make low-stakes bets like this in the past, but this particular instance definitely raises the stakes. No rule against bets though.
Please discuss below. Thanks
