Kristaps Porzingis

Kristaps Porzingis has overachieved this season. The mysterious 20-year-old Latvian has won three rookie-of-the-month awards and is sure to earn a spot on the NBA All-Rookie First Team.

Perhaps it is the competitive spirit of the Knicks forward that makes him a star. Exhibit A is this EA Sports FIFA trash talk video geared toward Sasha Vujacic.

We know you woke up craving a Porzingis-Vujacic barnburner, which is why we're so excited to bring it to you. What a scene in the Knicks locker room. The video is the Snapchat story of Kevin Seraphin (yes, that's right, D'Angelo Russell, Snapchat can be used for good). So we can conclude three of the Knicks four foreign players (Spaniard Jose Calderon makes way too much money -- $7.4 million this year -- to hang around these stooges) spend their free time playing FIFA together. Vujacic, 32, is from Slovenia and Seraphin, 26, is from France.

Porzingis claims to be the FIFA champion, although Vujacic did defeat him one game. Porzingis wants a rematch with Vujacic to "murder him" and "eat him like a gazelle."

Vujacic, whose worldly travels have taken him through two championships with Kobe Bryant, an engagement to Maria Sharapova and two Turkish Basketball League All-Star nods, says there are two sides to the story.

Michael Jordan had cards to be competitive with off the court. Kristaps Porzingis has FIFA.

Somewhere, Carmelo Anthony is not amused.
