Cleaning of the data

This clearly has to be filtered further joined, for example the Layup Shot 2 should be the same category as Driving Layup Shot I think. we can discuss this further.

For now, I found the 6 most tipicall shots made in the NBA, measure by proportion of shots taken overall (Prop). And also calculated the points per shot for each kind of shot(PPS).

ACTION_TYPE Prop PPS
Jump Shot 3 0.28 1.03
Jump Shot 2 0.18 0.59
Layup Shot 2 0.08 0.81
Driving Layup Shot 2 0.06 1.18
Pullup Jump shot 2 0.05 1.06
Floating Jump shot 2 0.02 0.93

Sortable table by team

Then I made that information for each team, as you can see, the team that is more monotematic is the Houston Rockets (no surprise there) where more than 40% of their shots are three pointers, you can use the arrows to sort by any of the given categories.Let me know if you think of something with this.

Are teams choosing their most efficient shots?

One question worth asking is if teams shoot more the shots that they are more efficient at (more pps).
