Efficiency Trajectories

I thought it would be interesting to track how team efficiencies not only evolve during a season but also from season-to-season. So, I built a tool to visualize the margin-based adjusted efficiencies here: https://www.hoopsci.com/efficiency-trajectories/ The animation speed can be controlled with the slider. The video download button may not work perfectly – it depends on each browser’s implementation. If you have problems, it might be easier to just screen capture the video,

Note: these efficiency numbers are not going to exactly match Ken Pomeroy’s or Bart Torvik’s numbers, since everyone’s got a little secret sauce to keep the efficiencies stable and reasonable in the early part of the season.
