He gets sandwiched between two guys and is spun around, losing his balance. He's facing the floor, literally on his hands trying to catch himself and people see this as some kind of planned trip he was waiting to do. His foot people think is trying to ruin this guys knee starts almost by his shoulder and he can not have a clue what's happening as he's facing the floor. This isn't his classic upper cut to the sack on a screen. It's incidental and some fan wanted to get clicks on twitter. Congrats to said twitter poster.
I'm not saying don't make fun of the kid (man?) for whatever you want, but it's sad the amount of attention people give an average basketall player in his 8th year. Maybe that's what he wants??
