Suplimental Signals

[Theisey]

That team-A has 11 signal means just that.... team-A has 11. It is not used up this way for anything else. Therefore the formation can be gauranteed.
Coaches had been sending in film time after time complaining about covered receivers or not enough players on the line. That has been reduced drastically by the punch back and use of team-A has 11.
If you have a better way that works for you, by all means continue to use it. I'll not complain.
