Signal for 11

[Theisey]

Both officials (R and U) can't forget to count. It's got to become so presnap automatic that you don't even know you are doing it.

I don't like the thumb-up vs thumb-down signal. On poorly light fields, it's hard to discriminate between the two from the wing position as we look for this from the "R"
Just a simple fist will do for 11, and an open hand (or both hand) to the chest will do for 10 or less.
