This question may seem like comparing Harden and Curry, but in reality, it involves the roles and responsibilities of basketball players on different teams. First of all, I would like to point out that it would be extremely one-sided to say that Curry only needs to score. As the heart of a team, Curry's mission is much more than scoring. He needs to organise the team's offense, control the tempo of the game, and play an important role on the defensive end.
Now let's talk about Harden. Harden does have a lot of work on the team, scoring, playmaking, defending, everything. But that doesn't mean he's better than Curry. Basketball is a team sport, and each player's roles and responsibilities within the team vary from team to team. Some teams need players to take on more offensive tasks, while others need more defensive tasks.
In terms of individual ability, Harden and Curry have their own strengths. Harden's scoring ability and playmaking are stronger, while Curry's projection ability and impact on the court are not negligible.
Finally, I would like to say that both Harden and Curry are outstanding representatives of contemporary basketball. We can't just judge who is stronger based on their role and tasks within the team. Basketball is a team sport, and winning requires the effort of the whole team. Every player is contributing to the team's victory, and that's all that matters.
