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.
I played Team Handball. Best, dynamic team game, wildly popular in Europe. Results are in 20 - 30 goals. If they had offside rule, it would be in 4 - 8 goals. Boooring!
Games become faster, more goals, more interesting. Some stale soccer games, you have team pressing most of the time, only get beaten by one lucky goal by another team. After 90 minutes of back and forth kicking.
I played soccer, but found Handball much better, you use hands and feet in interesting game. Too bad it is almost unknown in US.
