You are wronger. The game would adjust, more dynamic, more goals, no bitching about boring game. Team Handball and Basketball use it.
Suggest you actually play or coach the game. Modern soccer is watchable due to the offside rule. Actually (as a coach) the fans may be bitch but we generally accept the offside call as part of the game and build defensive strategies around it. Like an offside trap. Actually experts on the game believe it makes the modern game. One reason is the high quality of modern athletes. You do not want the offside rule play grade school kickball they do not have offsides.
