Stephon Castle is set to face Jalen Brunson in the NBA Finals, and Brunson is wary of Castle's defensive prowess. On Tuesday, Brunson said Castle is great and has special intensity and tenacity.

What happened?

Castle stymied Shai Gilgeous-Alexander in the Western Conference finals and has also had success against other top players. Brunson has had to put on his cape often this postseason, but the moment might call for it as the Spurs figure to be far more competitive.

Castle has had success against Brunson in a limited sample size, holding him to 3-of-11 shooting when matched up. Castle said he tries to be physical with Brunson and crowd his space without giving him angles.

Why it matters for Stephon Castle

Castle's defensive skills are gaining attention, and he just missed making the NBA All-Defensive team this season. Spurs coach Mitch Johnson gushed over Castle's defensive prowess, saying it takes him to rare territory.

Johnson stopped short of comparing Castle to some of the league's greatest names, but said his output of energy is similar to Victor Wembanyama's. Castle is basically in the middle of every single play for the Spurs offensively and defensively.

What comes next?

The Knicks will have to find a way to exploit the Spurs' defense, but it won't be easy. Brunson said the Spurs are very physical and able to pressure on the perimeter, and having Wembanyama down there on the weak side creates havoc.

The series begins on Wednesday, and Brunson will have to keep his pulse on his team. Castle's defensive skills will be a key factor in the series, and it will be interesting to see how the Knicks respond.

The Spurs have a multidimensional team with many players who can switch onto Brunson for stretches. Brunson has had to keep his team in the game often this postseason, but the moment might call for it as the Spurs figure to be far more competitive.

Castle's intensity and tenacity make him a great player, and his defensive skills are gaining attention. He has had success against top players and will be a key factor in the series against the Knicks.
