NCAA Umpire Mechanics

[Theisey]

Unless this is a "conference" thing, the "R" should rarely need to touch the ball after a down ends.

The U rarely will help out at the sidelines either. That's what the R and the two deep officials (F and S) do all day long with their respective partners (L and H). U can hold back to get the approximate succeeding spot and dead ball officiate with the middle official (B) from the inside out.
