The felony charges against Terrion Arnold are so serious that the Detroit Lions already cut him. But the charges are not too serious, apparently, for the Giants to work Arnold out. Arnold is facing four counts of kidnapping and four counts of armed robbery, which carry a potential sentence of life in prison. The Giants' corner room is a major concern. Resorting to a workout with Arnold, though, associates the Giants with a player who is facing life in prison if convicted of his alleged crimes.
