I entirely agree with Shaq here:
Shaq's advice to LeBron: Don't chase rings
Shaq says that LeBron's legacy is set whether he adds any more titles or not.
O'Neal said in the interview. "He done already passed up legends; he done already made his mark -- he has three rings. His mentality now is probably: I want to get four before Steph (Curry) does. That's probably his mentality now. But if I was him, I wouldn't be trying to get four, five and six because it ain't going to matter. It's just something else to talk about, something else to add to the pages. He's a legend, talked about as who is the best between he and Michael Jordan, so he's set."
