Yup the game would be wild, counter attacks would become a lethal weapon in the hands of poorer defensive teams with no super stars,I agree totally with you. Why not forgetting about offside? it would open up the game so much. Defence would adapt and stop playing to voluntary move forward to make attacks players offside.
Just like on a free throw let’s move the game with no offside!
and it'll reward speedy players instead of punishing them.
