The New York Knicks are facing challenges in their pursuit of a defensive-minded guard after Dante Exum opted to re-sign with the Dallas Mavericks instead of joining the Knicks. Exum, the fifth overall pick in the 2014 NBA Draft, showcased a solid season with the Mavericks, averaging 8.7 points and 2.8 assists, alongside his reputation as a strong defender at 6-foot-5. As the Knicks focus on improving their roster, they have already added offensive talents like Jordan Clarkson and Guerschon Yabusele but still lack a defensive stopper off the bench, prompting speculation about potential moves including free-agent Ben Simmons.
