I think the Mets should sub in another player on a true prospect contract, because I don't think Graham Godfrey qualifies since his contract is $1m (2011).
B) Players eligible for a waiver trade should be mentioned in the rules. For simplicity, and part realism, we should allow any player on a P-n/a contract to be traded in addition to players that have cleared waivers or been claimed on waivers.
