The Portland Trail Blazers were the first team to use the "amnesty clause." They still have to pay Anderson, but his salary won't count at all towards the luxury tax penalty. (If a foreign players gets waived according to this rule, would it be the "amnesty international clause? Sorry.)
Now Derek Anderson gets paid for a team he doesn't work for, and if he signs with another team, he'll still receive all his money from the Blazer plus the money from his new team's contract.
By the way, once it was announced that Derek Anderson was released, the Yankees gave him a call. Cashman is hoping one of these released players will work out for him.
