dumb guy soccer question:
why when the ball goes out of bounds do both teams just raise their hands? At least in American sports you point in the direction you think the ball should go
They're raising their hand to mimick the assistant referee raising his/her flag. It's also what an AR would do if there were no flags. Players will do this to call for the ball to be called out, asking for offside, or for a foul call.
This was actually a point of contention in our game. On the play that Bale drew the foul in the box, it appeared the ball went out of bounds right before. Robinson "Jedi" raised his hand, wanting the ball to be called out, it wasn't, then Zimmerman went Pat Bev on Bale
