RJ Barrett chose Kristaps Porzingis as the opponent he would most like to dunk on.

The former Knick didn’t completely dunk on the prized rookie in response, but let him know it won’t be easy.

“He said he wants to dunk on me? That’s fine,” a smiling Porzingis told reporters in Dallas on Thursday. “I’m a shot-blocker. I don’t know what some people are saying. I’m one of the best shot-blockers in the league and I’m always up for the challenge. I think that’s a pretty good goal for him to try to dunk on me. That would be cool. I respect that.”

Perhaps trying to get Knicks fans to like him even more, Barrett got things started in a Bleacher Report “Ask Me Anything,” when a fan asked who he would most like to posterize.

“Let’s go with Porzingis,” Barrett said.

The comment made its way to the Mavericks facility, where Porzingis is gearing up to play his first game since tearing his ACL in February of 2018. In between, he forced his way off the Knicks in a trade to Dallas.

Porzingis averaged two blocks per game in three seasons as a Knick. Barrett will get his first chance to dunk on the 7-foot-3 Latvian when the teams meet Nov. 8 in Dallas.
