I created a package of charts comparing each player’s Advanced Statistical Plus/Minus (ASPM) between 2011 and 2012 (through the All-Star break). You can select any player, anywhere in the viz, and the player will be highlighted on all of the other views, for both 2011 and 2012. You can also select multiple players (hold down CTRL) and compare them.
Read the full explanation and derivation of ASPM to understand the numbers.
Enjoy!
