Each NBA Basketball Team Heat Map [obsessionism.com] shows who was coaching the basketball team that year, who were the top offensive players on the team, and by how many possessions each team won or lost over a 5 year period.
The overall goal of the charts is to be able to observe how time, coaches and players create point spread trends. Win percentage paints a narrow picture of how key personnel react to being put into different game situations. Year-over-year trends may help people see why their team is gaining or losing ground to the competition.
Each color is a point range that the team won or lost by in that year. Green to red bars are wins, while blues are losses. The lower area provides team information for each year. The right bar shows the average share of games won ad lost by each 3-point range over the last 5 year in the NBA.
One of the discovered insights is how certain teams and coaches are more likely to win by 3 or fewer points than they lose by the same margin.
