SAN ANTONIO — One of the Knicks’ biggest postseason contributors came into the season on a non-guaranteed contract.

Through the first two games of the NBA Finals, Landry Shamet has scored 13 points off the bench in each game, hitting key 3s for the Knicks during their second-half rallies.

His Finals performance comes after scoring 30 points in the last two games of the conference finals, including a 16-point performance against the Cavaliers in Game 4 when he hit all four of his 3s in the clinching game.

While the Knicks have built a championship-caliber roster through the free-agent signing of Jalen Brunson and multiple blockbuster trades, the team has also developed depth by hitting on second-round picks Deuce McBride, Mitchell Robinson and Tyler Kolek, and fliers like Shamet.

After averaging 9.3 points per game on 44 percent shooting, including 39% from 3, Shamet made his case as the best player in the NBA this season signed to the veteran minimum of $3 million.
