I read this article on ESPN talking about Pau's trade value. In the article they posted a lot of interesting stats that proved that (A) Pau is indeed getting touches in the post and (B) that Pau needs to work harder.
Gasol has been used in 25.9% of the Lakers plays on offense so far this season. His highest rate since being traded to LA.
In 2010-2011, Pau was at the peak of his powers (before the Dallas mental collapse). He was named to the NBA all second team and was an All-Star.
This season Gasol has made 33.9% of post up shots and averages .68 points per play, the worst in the NBA. Historically Gasol averages around .9 points per play in the post.
% of Post up plays
2010-2011 - 39.5% (of total plays)
2011-2012 - 28.7%
2012-2013 - 23.0%
2013-2014 - 36.2%
As you can see, 36.2% of all Pau's shots are coming in the post. The fact that only 33.9% of his shots are going in is the real problem here, not D'Antoni.
D'Antoni recently told reporters that Pau just has to work harder and he is absolutely correct. I'll give Pau some credit where no else is doing and say that he has stepped up his defensive rebounding this season, but the offensive end is where he struggles again.
Pau is not getting easy opportunities like he has done so frequently in the past (like tip ins, layups, cuts to the basket, etc).
Here are the % of plays in which Pau has cut to the basket over the past 4 seasons.
Cuts to the Basket
2010-2011 - 15.1%
2011-2012 - 14.7%
2012-2013 - 11.8%
2013-2014 - 9.8%
As you can see, Pau has gone from 15.1% to 9.8% a significant decrease in movement and energy.
The other half of Pau needing to work harder comes on the offensive boards, where Pau has only scored 15 points this season from offensive rebounds. In contrast, Jordan Hill has scored 54 points.
Here are Pau's offensive rebound rates in relation to his total plays this season, as you can see below, Pau's offensive rebounding rate has dipped to under 1/3 of what it was previously.
2010-2011 - 10.3%
2011-2012 - 10.2%
2012-2013 - 9.8%
2013-2014 - 3.2%
