After being selected with the No. 4 pick in this year's draft, to a smattering of boos from New York fans, Porzingis was deemed a project - a player whose long-term potential would outweigh what he could immediately produce.
Instead, after a 29-point, 11-rebound performance in a win over the Charlotte Hornets, Porzingis is already way ahead of what people thought he would be capable of in his rookie season.
Porzingis, of course, knew this was coming. He told reporters after reaching his career-high points in the win, "Everybody was saying that I was a project, to wait a few years. I will get better in a few years, but I knew I was able to play right now. That was my mentality."
Carmelo Anthony said of Porzingis' big night: "I knew he was ready … I'm pretty sure this will be the first of many that you all see."
Each game, Porzingis has shown off a different aspect of his diverse game, gradually looking more and more comfortable on the court.
His put-back dunks have made him a mainstay in the highlight reels:

On Tuesday night, he showed off less flashy plays, but nonetheless impressive moves, like a "Dream Shake," made famous by Hakeem Olajuwon, for a baseline jumper:

Or muscling among two Hornets players for an offensive rebound, put-back layup, plus the foul. Impressive, considering his slender 7-foot-3, 240-pound frame.

Down the stretch of the game, Porzingis heard chants of "Por-zin-gis!" and perhaps sarcastically "M-V-P!" from the MSG crowd.
While there's a clear sense of confidence from him, he clearly is humbled by the attention and appreciation, too.
As Yahoo's Dan Devine notes, Porzingis' 29-and-11 game before his 21st birthday puts him in elite company. Some of the other players to do it at such a young age: Shaquille O'Neal, LeBron James, Kevin Durant, Dwight Howard, Chris Bosh, Carmelo Anthony, and Anthony Davis, to name a few.
Others around the NBA world are just flat-out impressed with what Porzingis is doing already:
I had Kristaps Porzingis 3rd overall in my first big board that I released last January. He's exceeded even my own expectations.

Porzingis has changed the oxygen at Madison Square Garden. There's no stat for that ... but NO ONE thought he could do so in his first month
