No, you didn't, but that's fine.
Regarding stats, I am referring to every advanced metric - RPM, RAPM, PIPM, BPM, VORP, and VORP WS - that have him ranked as one of the ten worst players in the league. He has a 55% true shooting (average). His net rating was -1.1 with a 37% TS%, November was -19.9 with a 48.8% TS%, December was -7.9 with a 55% TS%, January was -5 with a 58.5% TS%, and February was a -13.8 with a 61.1% TS%. So yes, his shooting has improved every month, even though it is not reflected in his advanced metrics.
A big reason why his January and February (10 games) are so impressive is that his assist/turnover ratio (1.2 assists to every turnover) has improved along with his shooting... but that number is still pretty bad, especially with a 20%+ usage. He has gone from a horrific playmaker to a below-average one, but his shooting is definitely improving.
The huge, largest, absolutely terrible problem, though, is his defense. KPJ's opponents are shooting 8.6% better against him as the primary defender than on average and over the last fifteen games that number balloons up to 14.2%.
Basically, KPJ's last fifteen games show him as a phenomenal shooter, below average playmaker, and one of the worst defenders in the league. This is why his advanced stats have barely improved throughout the season. He is prone to turnovers and is a horrible defender.
Now, let me be very clear: I really like Kevin Porter Jr. and think he will be a very good player in this league. But it will take more than hard work and keeping a good head on his shoulders to do so, which was the initial post I was responding to.
I honestly am not trying to pick a fight, though it seems like you are, but I really do like KPJ. This idea that he is some franchise savior and just needs to work hard to become a superstar, however, is profoundly incorrect. He has the potential to become a superstar, but he also has a really long way to go.
