stop the play

[joe bonner]

I finished my first year of Freshman / Jr.Varsity. I also had the opportunity to work the chains for some of the State Champ playoff games. (AA & AAA) I am confused by some inconsistent whistles to A.)stop a play from starting or B.)stop a play that has just started . It is obvious when a O-lineman jumps prior to the snap. How about when a D-lineman jumpsand gets back , when two offense players are in motion, when 12 men are on the field ,or six men on the line. I have seen the play blown dead in each of these examples. I have also seen the play run through in each of the examples. I know, I know , get the rules book out and study!!! However you guys clarify things and make learning techniques fun.
