I'm not entirely sure about this. Yes, the Lopez brothers suck at rebounding. The past three years I referenced included two from Milwaukee but one from Philadelphia, where he was with Embiid and Simmons. In any case, the idea is that Gobert would take away Ersan's rebounds. One could argue that he isn't sharing the floor a lot with Gobert, and it would be Favors, but I'd be curious on his lineup data with who he shared the floor with in Milwaukee, because the past two years that he was with Giannis, Giannis was averaging 16.1 rebounds per 36 and 13.7 per 36 the year before. But his total rebounding % before Milwaukee was about 13%, compared to about 14% with Milwaukee. I'm in the minority here in thinking that he may see some 5 time.
Any way you slice this, though, he's a much better rebounder than anyone on our team that's not Favors or Gobert, even if we nitpick.
