He shot 3% better on a higher volume, which I would say is a pretty important improvement. Also, the number of players 21 and under who "take over games" is very short. If you want to compare him to the LeBrons of the world, then yes...he falls short (even at 7'3). Even our beloved Booker (who most experts seem to still rate behind Porzingis fwiw) hasn't led to consistent wins.
Also, let's take the 21-year-olds in history who have been able to take over games, put them on a team with Carmelo Anthony, and see how many take over.
Seriously...look over the great players in history at age 21. Making a statistical argument against someone ever being more than good based off of stats at that age is fruitless. And in this case, it's not even a good statistical argument. The kid is playing very well. He's not Lonzo Ball. We're not projecting. He's in the NBA. He's excelling. It's already a thing.
Not saying he is a lock for the Hall of Fame...but to discredit him based on his stats right now is a fool's errand.
Here are four players at age 21:
MIN FGM-A FG% 3PM-A 3P% FTM-A FT% OR DR REB AST BLK STL PF TO PTS
Player A:
26.7 3.6-8.3 . 436 1.4-4.0 .349 3.5-4.2.843 0.5 2.6 3.1 2.1 0.3 1.1 2.5 1.3 12.2
Player B:
34.3 5.9-14.1 .418 0.3-1.3 .221 4.0-5.1 .780 1.7 3.2 4.9 8.0 0.4 1.3 2.5 3.3 16.1
Player C:
32.8 6.7-14.9 .450 1.7-4.8 .357 3.0-3.8 .786 1.7 5.5 7.2 1.5 2.0 0.7 3.7 1.8 18.1
Player D:
31.2 4.5-9.1 .494 1.1-3.0 .374 1.8-2.2 .825 1.1 4.9 6.0 1.6 0.6 1.7 1.7 1.1 11.9
Looks pretty similar, right? Any of those stand out as particularly more impressive than the others?
Player A is 21-year-old James Harden
Player B is 21-year-old Russell Westbrook
Player C is Kristaps.
Player D is 21-year-old Kawhi Leonard.
That's the top 3 MVP candidates.
With reasonably similar minutes, Kristaps has the most points per game, most rebounds per game, most blocks, 2nd best 3 point %, and 2nd best fg%.
He's 7'3, so I get that rebounds and blocks and fg% are in his favor, but the point is these players are not in different leagues statistically.
Those three improved dramatically, and what happens over the next couple years means everything.
So does this prove Porzingis will one day be an MVP candidate? Of course not.
Does it prove that he never will be more than a good player? Far from it.
