I think it will be costly for them to trade him rather than just dump him for picks/TE
From CBA:
"If the player is waived from July 1 to August 31, then his remaining salary is paid over twice the number of years remaining on his contract, plus one. For example, if the player is waived on August 1 with two seasons remaining on his contract at $10.2 million and $10.3 million, respectively, then his remaining salary is paid over five years (two seasons times two, plus one), in even amounts of $4.1 million per year."
