Which one of these matchups would you pay to see?

I would give my right arm just to see Lebron James vs. Oscar Robertson. That would be a mind-blowing game. Oscar "The Big O" Robertson, the only player in NBA history to average a triple-double in a season and just missed by a hair in two other seasons. The only guard in NBA history to average more than 10 rebounds a game. One of only two players to lead the NBA in points and ists in a season. He was the prototype for future players like Julius "Dr. J" Erving, Michael Jordan, Kobe Bryant, and Lebron James.
