Can someone explain how a snap count works in football?
When a QB calls the play in the huddle he will call formation and usually numbers. For example, he might say..."Ron 32"...with Ron being the formation...it might signal Tightend to the right. The 3 signifies what running back (fullback or tailback) gets the ball and 2 identifies the hole. Each hole from center to tight end is given a number. Usually even # to the right odd numbers to the left.
Some start with center/guard gap being being high or low...for my example lets say the right center/guard gap is 8-guard/tackle-6/tackle/tight end-4 and outside the tightend is the 2 hole.
So the call in the huddle would be "Ron 32 on two". That tells the team the tight end is going to the right and the tailback is running a sweep around the right end on two.
NOW...the QB walks up to the line and looks over the defense and he will call out a color and a number. Green 22. The cadance would be, "Green 22, Green 22, set...HUT...HUT". That is how a snap count is done.
Now...the color/number/set/ready/hut/go or all different for different coaches and QB's.
The reason for the color/number/color/number is to allow the QB to change the play. Before each game it is determined that the QB will have a HOT call...usually RED.
So if the play call in the huddle is "Ron 32"...the tailback sweep around the right end...the QB might see the inside linebacker lined up outside the TE and need to change the play to in inside run.
The QB would then say, "Red 37, Red 37 set hut...hut"...now this changes the play to a tailback dive between the left side center guard gap...because the QB saw the backer moved outside leaving the middle open.
When you get into college and pro's...the snap count becomes more complex but it still means something. Same thing with the play calls and formations..but I can promise you this...the snap count has a lot to do with the play call, the formation, and the opportunity for the QB to change the play.
I hope that cleared it up for you
