No matter how many times you see Odell Beckham come down with the ball, you still have no idea how he did it. No one does. Not the NBC broadcast team. Not the millions watching on television. Not even scientists probably.
Not even the referee, who likely threw the flag partly out of some subconscious fear that this sort of thing was possible in reality. You can’t just break the laws of physics, Odell Beckham, and get away with it.*
And then, once you’ve picked your jaw up off the floor, some tech sleuth decides to post a blown-up picture of the catch, showing precisely how many fingers Beckham used to grasp the football (three). Again – off-balance, with the football behind him, without the use of any other part of his body to cradle it.
Naturally, the internet began discussing this at length, and the catch earned some high praise from elite company.
Beckham actually practised this move and other one-handers in the pre-game warmup,
He's also made a catch like this before, in college.
None of which explains how Beckham managed to procure the services of a wizard scientist to make such catches possible in our three-dimensional universe.
*The flag was actually thrown for pass interference on the defence, which makes the catch even more stupid. Beckham has no need for the mortal laws of football.
