Say what you will about Rudy Gobert, but there's no denying that he is a historically great defender. Gobert's four Defensive Player of the Year awards are tied for the most in league history. Even still, some people argue that Gobert struggles to guard smaller players on switches and isn't a good isolation defender.
Is Gobert one of the league's most versatile defenders who can guard every position like Bam Adebayo or Victor Wembanyama? No, he's not. Can he occasionally get exposed on isolations or switches? Yes, but so can everyone.
However, to say Gobert is a bad isolation defender who can't guard smaller players at all is factually incorrect, and this year is proof of that.
