I'm a first year guy. I've done about 60 games.
Not one T. Yes.. coaches complain, but I've yet to hear a magic word, or have them read a decible level that wasn't quelmed with a simple "thats enough coach".
Thats just me. I've come close... but they all seem to know that look that I give them... and they shut it.
I'm SURE I'll have to eventually, but havn't had to yet.
