Defense effectiveness in college basketball

Defense in college basketball is important, but why? The game of basketball is based around scoring more than your opponent. Anyone can jump up and shoot three pointers all day long, but will they make them?  The job of the defense is to make it difficult for an opponent to score. However, this can be done in two different ways:  force turnovers and limit a team to a low number of points. The effectiveness of a defense can be measured by the amount of ball possessions that end in turnovers or missed shots, but how much is too much? Is there a point at which forcing more turnovers or allowing fewer points becomes harmful rather than helpful.

College basketball defensive efficiency

The following is a study looking at the effectiveness of a defense in college basketball. It does not, however, look at single aspects such as zone or man to man. Instead it looks at all defenses together and attempts to answer the question:  how different defensive styles affect the number of points scored against them. The larger the difference between points scored against a team and the average value, the more effective that defense is.

The following graph shows the number of points scored by an opponent at each efficiency level for both field goal attempts and three pointers attempted.  For example, a team with a defensive efficiency of 120 will allow its opponents to shoot about one point less than what they typically shoot.  In this case, that team will allow its opponents to attempt about three fewer field goals and two fewer threes than the average Division I team.  This is important to note because a team’s defense can look very good if it only forces a high number of misses rather than forcing an opponent into turnovers.

As seen above, defense can be extremely helpful to a team’s overall performance. However, it is important to note that defense is not the only thing that matters when it comes to scoring and stopping an opponent from doing the same. The following graph shows how much each part of a team contributes to the overcoming of an opponent by looking at the ratio of field goals attempted by a team to the number of points they scored against their opponent. The size of each part is measured in terms of efficiency. For example, if one team attempts about three more shots than another it can be said that this team has an offensive efficiency that is 120% of the other teams. This would be because they shoot about one point more than an average team and their opponent shoots two less.

Discuss the role of defense in winning championships

As seen in the graph above, a team’s offense has by far the largest effect on how many points their opponent scores. This means that if a team wants to be successful it will need to focus on playing better offensively rather than focusing too much on defense. However, this does not mean that defense is unimportant; it only means that it is unimportant when it comes to deciding who wins and loses.

Defense can be extremely helpful to a team’s overall performance, but every aspect of the game (offense, defense, rebounding, turnovers) needs to be considered when determining how well a team is performing.  For example, consider the following scenario: Texas A&M is playing an away game against the University of Tennessee. At the beginning of the game both teams perform equally well in each aspect and A&M goes into halftime with a 3 point lead.  However, in the second half they play poorly offensively and defensively and allow 20 points to Tennessee, but manage to score 25 themselves.
