most of you prolly know this already but im gonna throw it out there anyway...i see alot of posts where ppl ask how can you tell if its man or zone def.the 2 ways are 1...to come out in a bunch formation and see how the def comes out and lines up like safetys start to the outside and step in a little and etc...the 2nd and most obvious is the oldest trick in the book which is send a man in motion and see if the d.b. follows.well...the second oldest trick in the book is to come out in your man or zone def and when u see them motion a wr to figure out your def change it to the opposite of what your running while the reciever is in motin.at this point its to late for them to audible to a different play.i get many picks and stuff many runs this way.like i said most prolly know this but maybe itll help someone.
