You know what Im saying?" he said, via The Athletic. "I dont think Ive seen this. So, if there needs to be an investigation, great. There should be. I dont know. There should be. Until we figure something out."He then said he was "available to play."Rivers addressed Antetokounmpos comments after the teams 133-101 loss."The tough part about all this is that Im in the middle, and I have nothing to do with it," Rivers said.
