Brogdon has been a solid defender throughout his NBA career. He has a defensive rating of 112.6 in the 2022-23 season, which is a decent score. However, it's important to note that defensive rating is not the only metric that determines a player's defensive abilities.

In the 2021-22 season, Brogdon played in only 36 games due to injuries. However, in those 36 games, he was able to show off his ability to make plays on defense. He finished fourth in the NBA with 18.3 drives per game, showing that he's able to contest and defend against drives from other players. He was also ranked 12th in field goal percentage among players who drove at least seven times per game across at least 30 games, indicating that he can defend well against players who attempt to drive to the basket.

Brogdon's 6-5, 229-pound frame makes him a strong defender. He has a great wingspan, which allows him to defend against taller opponents effectively. Brogdon also has quick reflexes, which enable him to make quick moves and change directions easily. His size and agility make him a valuable asset for the Celtics defense.

One area where Brogdon could improve is his tendency to lean too much into the drive, particularly on a mismatch. This was noted in a review of his performance against the Detroit Pistons. However, overall, his defensive performance has been solid throughout his career.

In conclusion, while Brogdon's defensive rating may not be the highest, he is a good defender. His size, agility, and quick reflexes make him a valuable asset on the court. He's able to defend against drives and tall opponents effectively, and he's ranked high in field goal percentage among players who drive to the basket. While there is room for improvement, Brogdon's overall defensive capabilities are impressive.
