Curry hits 31% on tightly contested shots and 43% on open ones these playoffs. So guarding him really well helps. He is not JR Smith or even Kyrie who often shoot better contested shots.
Like mention, Curry is going to score, we have to accept that. Kyrie can't literally just leave him open like Houston has, he just has to keep him honest. I am not as worried about Kyrie guarding him.
We just need Kyrie to be Kyrie offensively. If Kyrie is being himself offensively, then Curry's offense can be nullified since Kyrie is capable of matching him point for point. That's all we really want.
If Curry is going for 40, and Kyrie can only give us 15, then yeah, we are in big trouble.
