Every NFL team has at least one player who makes less than he should. It happens at skill positions, on offense, defense, and special teams. According to Bleacher Report, that player for the New York Giants is Andrew Thomas.
It’s hard to rate offensive linemen because they don’t have any real stats. They are graded based on how well they protect the quarterback, which is the job of each man on the line, so even those grades should be taken with a grain of salt.
