For the team trading the player, a trade is pretty much treated the same as the release of a player – the team is relieved of paying all future base salaries, but still must account for the bonus money that has already been paid to the player. Just like with the release of a player, the remaining unaccounted-for bonus pro-rations will accelerate and count against the team’s Salary Cap.
For the team acquiring the player, a trade means that the new team acquires the player’s remaining contract, but does not have any liability for any bonus money previously paid to the player.
