I tried it.Grab 3 of your friends. Tell 1 to stand in front of you, tell another to start rushing at you from 3 feet away, and jump over them both to sling a basketball 40 feet away to the third guy before they can steal it from you
Let us know if you can do that without your legs swinging out
I gotta say, the kick looked intentional to me. That is in no way a normal movement in that situation. So it is at a minimum a flagrant 1. And once you get to it being intentional, now the question is whether it was aimed for the family jewels or not? I can see how the refs got there.
You obviously dont watch much basketball. Many players have perfected the leg kick while taking a three point shot. It often gets a call against the defender.
