A league soccer hard to watch

I am finding the a league very hard to watch the standard of soccer appears to be very low and the coaching tactics very lack lustre. Surely they practice taking penalties out side the box.  When a penalty is taken out side the box you can bet it will just get kicked harmlessly over the goal. Why is it the first thought of A league sides to gain possession and kick it back to the goalie even when behind on the score board. I also don't understand teams that fall behind failing to get more players towards the goal. It appears that teams are more worried about letting another goal  in than scoring a goal them selves. In all other sports teams will take risks in a last ditch chance to try to get the points. Why is it when a team is behind and they get a penalty the defenders out number the attackers 2 to 1.
