NBA Most improved Player

I was watching a Warriors game last week and commentator Jim Barnett said something to the effect of “Stephen Curry deserves to win the most improved player award as well as MVP.” While it’s clear that Steph has made pretty large improvements especially in scoring per game, I think it’s pretty tough for such a high performance player to improve more than the rest of the league.

I decided to take a quantitative approach to this nomination by comparing player stats across points, assists, rebounds, blocks, and steals per game between the 2015 and 2016 season for each player.

The approach I took was pretty simple. I calculated the percent change on each of the categories and summed the changes up for each player for an equally weighted average change which I sorted on. Results of the top 100 most improved players as of 1/25/16 are listed below.

Interestingly, Stephen Curry barely made the top 100 primarily because his blocking has decreased. This result pointed out a flaw with my methodology. Categories like blocks generally have a much lower value than categories like points per game; therefore, the BLKPG has a very wide spread of percent changes relative to the others. For instance, going from 1 blocks per game to 2 is a large percent change, while going from 25 points per game to 30 isn’t as large of a return. So an update to the model that I’ll consider is weighting the average percent change by the average value of each category so that small changes don’t overpower the categories with generally larger values.
