Lebron wasn't going to surpass MJ even if he bullied his way to a finals win. In fact, this finals showed how good Lebron is and how crappy the team he played for is, and should forever quash the rings argument as it perfectly illustrates that winning is purely a team accomplishment with contributions from individuals. The failure of management shouldn't fall on the shoulders of Lebron.
That said, I am not sure about >>>>, MJ is about >> Lebron.
Now if Lebron wins the next 6 championships averaging 40/12/12 in the playoffs, shooting 60% from the field, and put in 4 blks and 3 stls, he would be the GOAT, but that's not likely to happen.
