Yesterday I outlined a method for determining how similar the quality and arc of two players' careers were -- in case you missed it, the basic gist was that I minimized the sum of squared differences between year-by-year Win Share totals for any two players to find the best matches. I was surprised/overwhelmed by the response we got, so today I decided to take it a step further and try to match players' offensive and defensive Win Shares by age (instead of just total WS by season # of the player's career), which should give better matches than yesterday's method. Also, I felt old-school players were being shortchanged by a shorter schedule, so I pro-rated everyone's totals to 82 games, including this year's in-progress WS totals.
With those changes in mind, here are some of the players we looked at yesterday (active players are through current age):
As was the case yesterday, I'll take requests until Justin makes a tool that allows you to make these kinds of comparisons on the site.
