No one knows for sure what LeBron James will do next summer when he becomes a free agent. Even Cavs owner Dan Gilbert is unsure of James' intentions. According to ESPN's Jackie MacMullan, when the Cavs were working out the details of the Kyrie Irving trade with the Boston Celtics, Gilbert asked James if he plans to re-sign with Cleveland next summer. James essentially told Gilbert that he couldn't give him an answer as the Cavs superstar wouldn't commit to re-signing.
