Giants linebacker LaVar Arrington equated the players union with organized crime Wednesday, 24 hours before he was scheduled to testify before Congress at a hearing involving his former agent. Lawmakers will be looking into the Players Association's suspension of Arrington's former agent, Carl Poston, stemming from his handling of a contract the linebacker signed with the Redskins near the end of the 2003 season. Arrington contends the union acted unfairly in taking away Poston's livelihood.
