What is a four point stance in football?

Feet and hands count as 'points'. A four point stance is generally associated with defensive linemen and means the lineman has both hands on the ground at the line of scrimmage at the time of the snap. Obviously, the lineman will have both feet on the ground so that counts for two 'points'. If a lineman also has both hands on the ground, that would be two more 'points' for a total of four. A three point stance is when the lineman has one hand on the ground. A two point stance is where the lineman does not touch the ground with either of his hands.
