I don't think I've had a 50+ foul game yet. I did have a very sloppy frosh game about a month ago that had about 20+ fouls in the first half. My partner (being even newer than me) was calling some ticky-tack stuff and I had a few of my own that probably didn't help.
We agreed during halftime to try and call less fouls and I think we did minimize it to "less than 20" in the 2nd half. (how much less, I don't remember).
The funny thing was that both schools were catholic schools. One was a city school that has had pretty good frosh teams in the past few years (not this year). The other school is from the suburbs and they have a fine varsity squad but the frosh weren't all that great.
What made it worst (and I hate this about a lot of games in our area), is both teams were "trying" to press. With a lack of quickness on the defensive end, and relatively few ball handlers on both sides, it made for a long dragged out affair.
