The top box here is Amar’e's Synergy breakdown from the 2010-11 season and the bottom box is this season. Take a look at his play type distribution. Plays that would get him shots closer to the basket, like Post-ups and plays where he is the P&R Roll Man have taken a steep decline. Post-ups constituted 12 percent 0f his possessions last season and that number has dropped down to 8.4 percent this year. Similarly, P&R Roll Man possessions accounted for 9.6 percent of his total possessions last season and that number has dropped to 8.6 percent this year. By contrast, Spot-ups, which accounted for only 10.1 percent of STAT’s possessions last season, have shot all the way up to 18.1 percent, and Off Screen plays have risen from 4.9 percent of his offense to 7.3 percent.
Spot-ups and Off Screen shots generally tend to come farther away from the basket than Post-Ups and P&R Roll Man shots, which explains why his FGA from the shorter locations (At-Rim, 3-9 feet, 10-15 feet) are declining but his Long 2′s (16-23 feet) have stayed pretty steady.
As you can also see, in each season Amar’e has shot a worse percentage on both Spot-ups and Off Screen plays than he has as a P&R Roll Man. His effectiveness on Post-ups has also taken a dip this year (down 18.5 percent from 53.4% to 34.9%), which can help explain the 17.7 percent drop in his FG% on shot attempts from 3-9 feet from the HoopData graphic above.
The presence of Tyson Chandler as the Knicks’ primary screener in the pick-and-roll has led to Stoudemire being used much differently this year than in years past
. More often, he’s an outlet man coming in behind the primary action to stretch the defense or is spotted up in the corner for the same reason. This has led to him taking a higher percentage of outside shots than he normally does, shots that he is also hitting at a lower than normal percentage, and explains the decline in his overall FG%.
