I believe he caught it. I thought he caught it when I saw it live and I've seen nothing to lead me to believe he didn't catch it.
But I'm telling you - on the official stats sheet, it is logged as an incomplete pass.
One of the things Kalani said that the conference is looking into is Robert's catch - I'm assuming that is the one they're talking about. And I hope he gets credit for it. But the official statisticians didn't log it as a catch - which is why the box score play-by-play describes it as an incomplete pass.
