If you've been following the Minnesota Timberwolves closely this season, you'd know the non-Rudy Gobert minutes have been a massive problem. The Wolves are 16.4 points per 100 possessions better with Gobert on the court defensively, a number that puts Gobert in the 100th percentile. To put this another way, the Wolves have what's equivalent to the league's second-best defensive rating (108) with Gobert on the court and the equivalent league's worst defensive rating (124.4) with him off the court.
Without Gobert, the Timberwolves turn to lineups with Julius Randle and Naz Reid. Despite their offensive gifts, neither player is a very good defender, and they both particularly struggle as rim protectors.
