I am curious, but how do buyouts work when another team is paying for them? Is the buyout cost split between the two (you pay 75%/etc. of what you were paying, the other team pays 75%/etc. of what they were paying)?
You could just have the current owner pay the whole hit and leave the cash adjustment alone, but that could cause problems with teams gaining cap by trading for and cutting players. For example, if I have a player making 4m and it is all paid by another team, then this method would mean I buy out the player 3m but still get paid 4m to cover his salary.
