In September, New York Knicks rookie RJ Barrett said he wants to dunk on Dallas Mavericks power forward Kristaps Porzingis this season. The new Mavs star, of course, began his NBA career with the Knicks.

Speaking to Dallas reporters on Thursday, Porzingis said he's one of the best shot blockers in the league and is looking forward to the challenge of blocking Barrett at the rim when the Knicks and Mavs play:

Kristaps Porzingis and the Mavs come to Madison Square Garden on Nov. 14. That's when RJ Barrett will have his first opportunity to dunk on KP.

In 186 games with the Knicks, Porzingis averaged 17.8 points, 7.1 rebounds and 1.3 assists. Barrett is the new face of the Knicks franchise now that Porzingis is gone. The lefty put up 22.6 points, 7.6 rebounds and 4.3 assists per game last season at Duke while shooting 45.4 percent from the field, 30.8 percent from beyond the arc and 66.5 percent from the free-throw line.

The Mavs gave Porzingis a five-year, $158.3 million deal this summer. The organization is looking forward to KP and Luka Doncic playing together. The Mavs envision Porzingis and Doncic being a lethal dynamic duo for the next decade.

It’s going to be interesting to see what type of reception Porzingis gets at Madison Square Garden when the Mavs come to New York. Knicks fans loved KP, but his trade request might have changed things.
