I apologize for the confusion. As of my last update, the Miami Heat and Oklahoma City Thunder have not faced each other in an NBA Finals series. The NBA Finals is a series played between the Eastern Conference and Western Conference champions. The Miami Heat are part of the Eastern Conference, while the Oklahoma City Thunder are part of the Western Conference. For them to meet in the Finals, they would need to win their respective conference championships. If you are interested in specific matchups, player statistics, or historical data, I can certainly help with that information. Please let me know how I can assist you further with NBA-related inquiries.
