I created a Tableau visualization of all 10,000+ TS-USG data points, which includes all player-seasons since 1980 with greater than 100 FGA in a season. Allow me to give you a virtual tour, before you go off and play with the data on your own (be careful!).
Think of the big blob of data points roughly as a clock. Let's go around counter-clockwise. When you explore the Tableau viz, you can zoom in on data points, and click on individual points to see more details, such as the year, team, and age of the player.
Extremely High Usage, Moderate Efficiency
High Usage, High Efficiency
Moderate Usage, Extremely High Efficiency
Extremely Low Usage, Moderate Efficiency
Extremely Low Usage, Extremely Low Efficiency
At least these guys didn't shoot too much.
