Early Monday morning, ESPN reported the NFL is considering a rule that would eliminate the chop block for the 2016 season. Your initial reaction might be, "I thought the chop block was already illegal," and you'd be right … kind of.
The NFL rulebook defines the chop block as such:
A chop block is a foul by the offense in which one offensive player (designated as A1 for purposes of this rule) blocks a defensive player in the area of the thigh or lower while another offensive player (A2) occupies that same defensive player in one of the circumstances described in subsections (1) through (10) below.
