This debate will continue for years to come...and it's already getting really old, really quick...
Both great players. Leave it at that. Whoever wins MVP, kudos to them. If either one wins the NBA Championship, they're not going to care about the MVP award or who others consider the best player. You don't play to be considered the best by the ****ing media.
You play to win the game!
