The Facts: Claiming that the rights to a retired player cannot be traded, the NFLPA is expected to file a grievance against the trade that brought Plummer from the Broncos to the Bucs early Saturday. The time the trade was finalized is critical to the matter. If it was finalized after Plummer filed his retirement papers, which reportedly was Friday, then the deal could be voided.

Diehards Line:Even more critical, however, might be the roughly $5 million in prorated bonus money Plummer will have to pay back should his retirement, which he officially announced on his Web site Saturday night, stick. If the deal goes through, there is a chance the Bucs will be in line for that $5 million payback. If it does not go through, the Broncos likely would be owed the money. Also important are the rights to Plummer. Though he has announced his retirement, he could unretire at any point. The team holding his rights could then trade them.
