Unprofessional Comment ?

[Chess Ref]

I had a rivarlty game that went sideways. Girls JV . Home team just destroyed the Visitors. We called 32 fouls in the second half. 25 of them on the Visitors. 4 players fouled out. 5 technicals, 1 on HC. Visitors were just slamming into people in the 2 half. I have had a player go on tilt but never a whole team. It was not pretty. Home team kept their heads about them even though it was obvious what was going on.

So lining up for a free throw, again, about 2 minutes left and I say in a calm and pretty quiet voice to ALL the players lined up. Though I really only needed to say it to the visitors. "Let's try and not go totally stupid these last couple of minutes."

My question is that comment of mine over the line or not ?
