The U's are in the offensive backfield

This would be my major concern especially on the smaller size crews.

I worked the wing on a 4-man crew here in the UK a couple of days ago and was screened out on a reception. I had no clue whether the kid caught it or not (usually you have a gut feeling one way or another). Luckily I had a decent Ump on the day and when I looked across for help, I got eye contact and the slight affirmative nod.
