Not really. You dethrone a king, then you rule their kingdom. That’s what the Thunder will do. They have to take the throne first.
No doubt to it; the Thunder is a strong team. But eliminating the Spurs will not suddenly give them 20 division titles, or mean they made the playoffs in 24 of the last 25 seasons.
Win or lose, the Spurs will remain the most successful team of all time.
