They have #34 playing "enforcer" as he clearly has no basketball ability as well as being fat and slow. It was obvious he was going to try and foul out of the game, and this is not uncommon for high school teams to do. The coach knew what he was going in there to do.

Basketball is a physical game, and the types of fouls shown happen once or twice in almost every HS b-ball game. The chances of someone getting seriously hurt by the fat kid flailing his arms are the same as landing on someone's ankle. This player isn't dirty though, dirty players don't get caught (like John Stockton). He is just a bad player. Skilled dirty players, step on your toes, grab your shorts, elbow you in the ribs, slap your nuts, and any number of good dirty player tricks. Dirty players end up getting retaliation fouls against the other team all the time.

If the refs did call flagrant fouls on one of these I would choose #4 because he came down with his arm or the frustration foul by the kid who had the ball stripped because it was just dumb. Those hurt as the opposing team gets the rock back, and the coach would learn a lesson.
