It seems more and more likely that Mitchell Robinson will slide into the starting lineup this season. While the move should give the Knicks' defense a significant boost, it doesn't solve the issue of Mikal Bridges being the Knicks' point-of-attack defender.
Robinson is a fantastic defender, and starting him would accomplish many things. It would provide some serious relief for Karl-Anthony Towns, who would be able to avoid getting hunted in quite as many pick-and-rolls if he isn't forced to guard the opposing center and primary screen setter.
It would also free up OG Anunoby, the Knicks' most versatile defender, to spend more of his time guarding his own position while having the security blanket of a true rim protector playing behind him for the first time in his Knicks career.
