Had a problem similar to this working a parochial school league on Saturday, but different results. It was an 8th grade game (am I seeing a trend here???). One team is falling behind in points and racking up the fouls. Coaches for that team start griping a bit. I'll call them Team A. Happens A1 (their tallest player) gets whistled for pushing foul on B1. A1 had his forearm in B1's back, as A1 was coming from behind to tip the pass away from B1. Easiest foul for me to call, right? Well, go to report it, Team A coach looks at me and shakes his head. I reported it, turned to coach and showed him the forearm and told him what happened. Coach still didn't like it. Eventually, Coach started grumbling less. After the game, he actually came up and apologized for his grumblings. A parent from his team also came up and let us know we called an excellent game. Remember A1? His dad had the opposite behavior. He just looked at us from across the court, and shook his head and gave us that "go away" wave. I turned to partner and said, that dude has no guts to say it to our face.
