Most Improved Players through Win Shares calculations for last three years

[Spursfanfromafar]

Did a small statistical exercise trying to find out the most improved player this year.

Methodology -

Tried to calculate improvement in WS/48 (for all players playing atleast in their third year) as follows -

Improvement = WS1314/48 - ((4*WS1213/48 + 2*WS1112/48)/6)

WS1314/48 = Winshares/48 for 2013-14 and so on.


Qualifiers -

a) Considered players who have played more than 500 minutes this season
b) Considered only those players who are more (and under 80th percentile of win shares this season. I use this to give more weight to good players this season than the slightly good ones.
b) Disregarded players who had a drastic fall in their WS/48 in year 2 (2012-13) because of injury or whatever (for e.g., Kevin Love, Michael Beasley etc).
c) Considered players who are playing in atleast their third year so as to account for rookie growth.

And here is the top 15-
