Never? Soccer has throw-ins, and goalies do use their hands.
Oddly though, I am suddenly in the mood for women's tennis....
Yes, but do you think (I don’t know, not knowing the game) that tossing the ball into play is a big deal? The fact that the goalies can use their hands does not seem important to me in that they represent just a tiny fraction of the players, all of whom cannot use their hands—aside from the minor point above.
I mean, contrast that with baseball in which the players both throw the ball, catch the ball, and hit the ball by use of their hands, all of them. I think that it’s ludicrous to think of soccer as skilled when they are tasked with running down a field and kicking a rather large ball; contrast that with someone holding a bat and trying to hit a small object traveling at speeds in the area of 100 mph, without knowledge of whether the pitch will be thrown with tremendous velocity, off-speed, curving, dipping, all the tricks of the pitcher, who is fairly close to the batter.
I see no parallel in the skills displayed. But then again, the two of us probably wouldn’t agree on much of anything in terms of sports.
The ball is thrown in with the hands if it has been kicked outside of the field, and the goalies use their hands to throw the back to players.
