Box out or no call? (Video)

[BryanV21]

The red player appears to jump backwards... not straight up/vertical. And when coming down the white player landed on the red player, and the red player bent over... for whatever reason. So it looks like no-call. Although, the white player was pushing the red player under the basket while the ball was in the air.

However, I can see how the white player may have been pushing still while the red player jumped, thus making it look like the red player jumped backwards and not vertically.

I honestly can't tell. Guess you had to be there.
