If you both over bid on the player (say bidding 1.5m each on two players of 600k and 800k max value) then you would both break even on the transaction (since you're both exchanging $1.5m), but this would ensure no one else in their right mind would bid against you. That would be a clear example of how to easily arrange it, ensure no one else outbids you without putting up any of your own money, and breaking the rules.
