*rolls eyes*
People are complaining about Ibaka's lack of involvement in the offense as if they actually paid attention to the Thunder this year. Whoopty-doo, you can cite his touches per games. That's all you need to know about the situation, obviously.
You know why Ibaka's not involved more in the offense? Because he has a pretty mediocre BBIQ, a really limited offensive game (he's a phenomenal shooter, though his numbers have fallen off this year... has no post game... his handles are just above raw, to put it nicely), and almost no passing game to speak of. Donovan actually ran a lot of high PNR conduit stuff with Adams and Ibaka at the start of the year. Adams struggled a bit (but has become better as the year progressed), but Ibaka was struggling MIGHTILY. That was a huge part of his down year; he got off to such a poor start because he was struggling with his new role in the offense. Ibaka excels when the game is made simple for him: catch the ball, shoot it, dribble a bit and pass it off, and defend. He struggles when he's forced to make decisions on the fly. That has been the book on him for years.
"Ibaka's not being used enough and is disgruntled." Funny how you guys conveniently forget that basically everyone on the Thunder was injured last year, giving Ibaka a prime opportunity to step up with a larger role in the offense when KD and Westbrook were both out. What did Ibaka do? He responded by... basically being the exact same Ibaka he is when playing with KD and Westbrook. Ibaka's role is limited because his game is limited, not because he's not allowed to flourish.
