When an amnestied player gets a contract from his new team, is that money subtracted from what his old team has to pay him? If so, Perk could do his new team a solid for signing for the minimum.
Not sure what you mean. If he's claimed off amnesty waivers, the new team is responsible for what they bid, and the old team for the difference.
If he clears waivers, he's a regular FA and his salary is fully on his old team's books.
At least that's how I see it. Not sure how anyone is doing anyone a solid here.
