I think that you are taking the common criticism of Parker's weaknesses to an illogical extreme. Offensively, he is such an elite prospect- so skilled but also crazy strong, crazy smart, and more explosive than people seem to acknowledge... he's going to score and draw fouls like few others.
I don't think that's fair.
So far he has had absolutely no three point shot in the NBA (shot under 30% last year, and hasn't even taken a three this year), he's been completely incapable of getting to the foul line (Smart's Free Throw rate this year is 44% vs Parker's 8%), he's rebounded terribly (only 5.5 Rebounds Per 36 despite playing PF) and his defense, from what I've seen, has been far from impressive.
He will continue be compared to Paul Pierce and Carmelo Anthony as a pro.
I feel like a less athletic Tobias Harris might be a more realistic indicator of where Parker's ceiling lies at the moment.
I have never for an instant believed that he has Pierce / Melo potential. He might prove me wrong, but I doubt it. I think realistically he'll probably end up aroud an 18 / 7 /3 guy in his prime, which is by no means bad...but also a long way from Pierce / Melo territory.
I'd much rather bet on a player like that to learn how to play respectable defense and round himself out than bet on, say, Zach Lavine to figure out how to make a leap in every respect (except the literal one-- he can jump really nice, haha).
Mmm...
Sorry to break it to you, but Lavine's putting up Per-36 numbers of 21.4 points, 5 rebounds. 6.3 assists and 1.3 steals while shooting 45% / 41% / 89%.
He is far, far better than Jabari Parker right now. Like, it's not even remotely close.
To be fair Parker has only played about 30 games in the NBA so far so he deserves some time to adjust and hopefully catch up, but at the current point in time Lavine is making him look pretty bad.
