how many fouls is too many?

[Adam]

Two things that caught my eye.

You said you were calling fouls to send a message. Don't make a habit of that. Call the fouls to be sure but don't whistle contact just to send a message.

That brings me to the second point that caught my attention, your partner indicating there were some plays where you called a foul as the offense was getting around. Possession itself isn't a good indicator, but if the dribbler is getting around the defender, you possibly don't have a foul.

Your mention of "reaching" is another possible issue.

Just food for thought.
