After two preseason games, Garrison Mathews is playing himself into serious contention for the Knicks' final roster spot. Jake Fischer reported that he continues to hear that Mathews is a legitimate option for the roster spot, which was previously thought to be lined up for Landry Shamet.
Heading into training camp, the Knicks signed non-guaranteed deals with Shamet, Mathews, and Malcolm Brogdon. As currently constructed, they only have the roster space to sign one of those players to a veteran minimum deal. However, it has been rumored that the Knicks are exploring trade options to create space to keep two veterans.
