U for 34 years here---
Rich F is correct about those plays
where you have a very quick running
back and in a blink of an eye he is
right in front of you------ do not move !!
I've seen the runner's break a smile when
they see you there as a blocking "post"
for them.
Watch out for the quick slant passes---
I've never been hit, but have had a few
buzz by my ear.
I'm a big man (6'3"/270) and usually have
players bounce off me- but the bruises
seem to last longer as you get older !
One other important bit of advice----
do not bend down to pick up the ball
too quickly-- a player may not see you
and nail you with his helmet when he jumps up !
Use your voice to prevent "extra activity"
if the players know you are there, they are
less likely to try any "funny" stuff.
Keep the flag in your pocket for the BIG
things -- and have fun !!
