http://www.blogabull.com/2015/1/31/7956 ... -a-mistakePau Gasol was selected as an All Star starter by the fans. This is, honestly, a joke. Pau Gasol is the Bulls fourth best big man. Yes, fourth best. Behind Joakim Noah, Taj Gibson, and even rookie Nikola Mirotic. The idea that Gasol was somehow one of the best big men in the entire Eastern Conference is ridiculous. At first glance, it's easy to see why Pau has received this recognition. Pau is averaging 18 points, 12 rebounds, nearly 3 assists, and over 2 blocks in his roughly 35 minutes per game. Those certainly seem like All Star numbers. However, it's pretty likely that no one is putting up emptier stats than Pau Gasol is this season.
Offensively, the Bulls routinely force-feed Gasol isolations on the block, allowing him to post-up while everyone else mostly stands around watching him, not cutting, not moving, nothing, just watching. Pau goes to work down low and if he has a mismatch, he scores with relative ease. Put someone with some defensive skill in the post on Pau, though, and he is almost entirely neutralized. This has happened over and over this season. It happened recently against the Heat in Miami, as Gasol (along with Taj Gibson) was dominated inside by Hassan Whiteside, scoring just 13 points on 16 shots. In the Bulls' last game against the Cavs, with the defensively stout Timofey Mozgov as his primary matchup, Gasol went 4 of 14 from the field and scored just 11 points. In the Bulls' last game against the Washington Wizards' beastly frontcourt Gasol went 4 of 11 from the field and scored just 13 points in 33 minutes. Simply put, too often, Gasol's offense, the place where he actually provides some value, disappears when confronted with a tough matchup. Sure, put Pau on the floor with a depleted Bucks front line and he might drop 46, but against legitimate post defense, Pau does not shine the way a 7 footer with his size and skill should. He gets bullied.
Defensively, Gasol is an absolute trainwreck. Despite his heavy rebound totals, Gasol almost never boxes out anyone. His rebounding totals are primarily the result of his being around the rim for the vast majority of the game and catching whatever misses come off in his immediate vicinity. Pau's gaudy block totals result similarly. Gasol hardly ever leaves the immediate basket area to get out help contain penetration or to properly help rotate. Instead, Gasol hovers near the basket and, due to his height and reach, blocks a few shots here and there at the basket. Sure, there is some value in blocking those shots, but mostly Gasol hurts the defense in the same ways that Carlos Boozer once did (poor rotations, slow feet), without the value that Boozer provided in boxing people out and / or securing defensive rebounds.
The Bulls are still stingy at forcing tough shots, as they rank 3rd in the NBA at opponent effective field goal percentage and they still play defense without fouling. Almost all of their defensive drop off can be traced to the fact that they have fallen to 20th in opponent offensive rebounding rate; in other words, they aren't boxing out on the defensive glass. The rest can be traced to the Bulls being the second worst team in the league at forcing turnovers, falling from their previously middling ranks in that category. I suspect much of this is related to Derrick playing more (he hardly ever gets steals), Joakim not being as frenetic as usual (his steal rate is down from 1.9% last year to 1.2%), and again, Pau replacing Boozer (Carlos had a 1.3% steal rate last year compared to just .5% for Pau).There's also the issue of communication on defense. Say what you will about Boozer's defense, and it was often very bad, but you always heard him out there. When was the last time you heard Pau call out anything defensively? That stuff matters, and I don't think it's a coincidence that so many of the incumbent Bulls have cited a lack of communication as a primary reason for their defensive struggles. All of this is to say that a good percentage of the Bulls drop off defensively this season can be placed on Pau's shoulders.
Looking at ESPN's Real Plus-Minus tells a similar story. Pau is rated worse than Nikola Mirotic and Taj Gibson & outpaces Joakim Noah only slightly (Pau is +1.04 to Noah's +.69 per 100 possessions), but Noah has been significantly limited by his health all year. The Noah we've seen the last few games as he seems to return to health is a significantly better player than Pau.
