Don't get me wrong, I also think his performance has been disappointing. I just think a major part of that has been Hoiberg, his rotations and the role he has asked Niko to play in the offense. The top Bulls lineup (Net Points, >100 min) has Niko at the 4. Put him at the 3 and other teams are guarding him with smaller, faster guys, which would be fine if Hoiberg would let him post-up more, but with Taj and Pau at the 4 and 5 he's not getting many opportunities to do that. So you end up with him just disappearing for large stretches.
