CSP means Contract Supplemental Pick. In Madden, there is no way to split, give, or take over the Signing Bonus in trade negotiations. For example, a user could be trading away Saquon Barkley for a fair offer but not take into consideration that they will trade him away and receive a $15M dollar penalty; while the other user receives Barkley for less than $4M each year left on his rookie contract. Obviously the CSP is null and void if both users are trading players – to each other – that has the same cap hit. If you are trading with someone who is only trading you draft picks and no players, then ask for a CSP on top of the fair value for the player. An example of fair compensation for Barkley would be a 14th-22nd overall first-round pick. The reason this would be fair is because a 1st round 14th overall pick would be half of what the penalty is for Barkley’s rookie contract. If you are trading away a player and will incur a penalty, then look at the rookie contracts signed for each pick and find the pick that shows your penalty cut in half. That would be considered a CSP. If there is no penalty, then you do not need to worry about a CSP. If you cannot get a CSP trade, then think twice about trading away your player.
