7 players on the LOS

While I have never tried the 4 and 2 method, I believe I can safely say you may find our method to work a little crisper as, all the wings need do is look at the signal by the White hat and, then, count the Offensive backfield. It is really bang bang and pretty fool proof.
So, to recap our method. The R and U count the offense. R and U signal each other with a bent arm and a fist. (I as a Referee, will hold the signal up until darn near the snap.) The wings note the signal, and count the backfield. Prior to all this the H, L, & B count the defense and signal each other, Typically, they will signal each other right after the offense breaks the huddle.
I can tell you it sure as heck took longer to type this than it takes to do on the field.

The trouble with counting players in the backfield is that it's possible to be neither on the line nor in the backfield. I suppose the comeback to that is that because you're looking for players in such a position anyway (on the finding of which the formation is illegal regardless), you count the backs only if there's nobody in such a position. Is that in fact your answer?
