Frank Ntilikina looked happy on Monday as he joined the Dallas Knicks.

“A lot of familiar faces, players I played with before,” Ntilikina said at Media Day. “That makes it a lot easier actually.”

Ntilikina, the Knicks’ 2017 lottery pick, signed a two-year, $3.8 million deal on Sept. 17 with the Mavericks (the second year is a team option). He joins former teammates Kristaps Porzingis, Tim Hardaway Jr., Trey Burke and Reggie Bullock on “Knicks Southwest.” The Mavericks visit the Garden on Jan. 12.
