So LeBron just won the title, the NBA MVP and NBA Finals MVP. Who else has done that? I know that generally the NBA Finals MVP belongs to the team that won the title, but I believe there was an instance where that didn't happen.
This is actually a fairly-common occurrence over the history of the NBA, it just hasn't happened recently:
Jerry West, by the way, was the only NBA Finals MVP from the losing team. That was the first Finals MVP awarded back in 1969.
