PPG, or points per game, is the average amount of points scored by a player each game played in a sport over the course of a series of games, a season, or a career. It is determined by dividing the total number of points by the number of games played. For example, if a player scores 50 points in a single game, his/her PPG score for that day would be 50. The NBA is the highest scoring league in sports with an average of 100 points per game. Last season, it was the first time since 2003 that the NBA failed to lead all leagues in scoring. This can be attributed to the increased use of 3-pointers in basketball today; only 5 seasons have had more than 6 players shoot 3s per game. In addition to being one of the most exciting sports to watch, basketball is also a hard sport to play at a high level. Defense is key; without good defense, you won't be able to stop others from scoring. There are several ways to defend the ball handler when he has the rock; here are the three main types of defenses: switching, trapping, and hedging. On switches, the other team will switch every position on the floor, so the guard who used to have the ball will now have to face off against another guard or forward, while the center will be left alone with the original ball handler.
