His pick and roll defense is still pretty mediocre, as is his low post defense. His ball screening at times is a joke, he just simply stands there like a pylon without actually doing anything. I think the number is something around -8 or -9 per 100 possessions that the Raptors are while he's on the court compared to every other lineup. That's pretty telling. He's honestly like the anti Amir Johnson. Puts up the numbers without doing the smaller things while he's on the floor.
Like you said he's going to get paid because there aren't many quality big men in the league who are available, but I think you should try and watch guys like Marc Gasol, Noah, Asik, Chandler, Horward, Horford, Hibbert more. This is what the whole argument with some started from.
