If Kobe shot at Lebron-level efficiency from midrange, it would have lowered his career scoring by.....0.7ppg

If Lebron shot at Kobe-level efficiency from inside and on threes, it would have lowered his career scoring by....1.5ppg
And since Lebron is bright enough to concentrate his scoring on inside and threes, instead of shooting 57% of his shots from that low-efficiency midrange area like Kobe does, he picks up an additional 1.3ppg on smarter shot selection alone.
And that's how Lebron magically ends up with a career scoring average of 27.2, while Kobe's down at 25.0, despite them taking the same number of career shots/game and Kobe supposedly being a "greater scorer".
Do you even see the numbers you're posting? The vast majority of shots are taken from 0-3 feet, where Lebron dominates, or from 16-30 feet, where they're even. The two players only take 20-30% of their shots in the 3-16 foot range where Kobe has an advantage, and most of those are in the 3-10 foot range where the advantage is small.
Lebron beats Kobe 54% to 48% on twos AND 34% to 33% on threes.
But Kobe is the better scorer because he's got that least-used, low-efficiency area from 10-16 feet locked down.
0-3 feet: Lebron dominantly ahead, 73% to 63%
Even better, Lebron is good enough to take 35% of his shots there, while Kobe's only at 21%. So Lebron's getting the most shots where efficiency is the best.
Lebron picks up 4.6ppg over Kobe at this distance, 3.2ppg due to higher volume and 1.4ppg due to better shooting.
3-10 feet: Kobe slightly ahead, 45% to 43%
Both of them only take 12% of their shots from this range, so that 2% difference is basically meaningless.
Kobe gets an extra 0.1ppg over Lebron at his distance due to slightly better shooting.
10-16 feet: Kobe clearly ahead, 44% to 36%
This is where Kobe has the advantage...but it's fool's gold, because he takes 17% of his shots in this low-percentage range while Lebron only takes 10%.
So while Kobe's hitting 44% on 17% of his shots here, Lebron's doing much better by not taking nearly as many of these and getting close-in shots instead.
Kobe has an extra 1.5ppg over Lebron at this distance, 1.0ppg due to higher volume and 0.5ppg due to better shooting.
16-23 feet: Kobe barely ahead, 40% to 39%
28% of Kobe's shots, 22% of Bron's. Again, fool's gold for Kobe, because while he has a tiny advantage, it costs him FAR worse when he's dumb enough that his #1 zone is his least efficient zone.
Kobe gets an extra 1.0ppg over Lebron at this distance, 0.9ppg due to higher volume and 0.1ppg due to better shooting.
Three-pointers: Lebron barely ahead, 34% to 33%, but actually 51% to 49% on eFG% since threes are worth more
21.6% of Kobe's shots, 20.4% of Lebron's. (Lebron actually averaged more threes than Kobe until Kobe decided to shoot nothing but threes last year.)
Lebron gets an extra 0.1ppg over Kobe at this distance due to better efficiency, but it's mostly cancelled out by Kobe's slightly higher volume.
So Lebron gets 3.2ppg game over Kobe due to getting more shots at the rim, and 1.5ppg over Kobe due to better efficiency at the rim and on threes.
But Kobe picks up 1.9ppg over Lebron due to taking more low-% midrange jumpers, and gets an additional 0.7ppg due to better efficiency there.
Your entire brag about Kobe's better midrange shooting efficiency only buys him 0.7 extra points a game there.
