James's bounce you say is not the first in history, this is really difficult to say, but in the small forward position, that really first exists. Even now that he's 37 years old, it's not hard to get a flat-frame dunk, and his bounces are really scary. When I was young, I worked at a high altitude, and the tomahawk was even more handy. To sum up, James bounced on the small forward, that is 100% first, if you do not believe that you have seen these 5 photos, you can have the answer.
It was James' early dunk, when he wasn't that heavy and played quite spiritually. This time he played with one-arm dunks again, and his entire arm exceeded the basket. If his arm span is Durant level, maybe this jump, the upper edge of the rebound can be touched.
There are many traps in the NBA, but most of them are training or dunk contests. Because that gives you enough room to start, and then there's no defensive pressure, a lot of people in the NBA can do it. James flew directly from his opponent this time, and this dunk should be a perfect score for the dunk contest.
This is also the bounce of the Cavaliers 1.0 period, teammates pass the ball with James, that is not considering the passing height at all, how high he can jump, depending on the height of the teammate's pass. It was originally a misstep pass, but it was saved by James, and the shoulders were flat framed. It was this time that the save shocked the US media, and they couldn't help but ask, how high can James jump?
The free throw line dunks the NBA can do a lot, but in actual combat, it is so easy, it is James. This is a round in the final quarter of the game, the players' physical strength has been severely depleted, James still holds the ball and attacks quickly, and then completes the dunk one step away from the free throw line. This buckle obviously has room for manoeuvre, and if it is farther away, he may be able to buckle it.
When I say that 37-year-old James jumped so high, I guess a lot of people don't believe it, and the truth is that it happened. This jump really dreamed of youth, and James was completely out of gravity. Everyone else at 37 years old is floor stream, even matchbox height, only James is still in top state. This time the cap was even higher than when he was in his 20s, and James's bounce was terrible.
