These supposed remedies are mostly nonsense!  
The game does not need repairing; it is doing just fine. Most of these rules are very old by sporting standards, well over 100 years. Leave the rules alone. If Soccer is not your cup of tea, watch something else! I would love to incorporate more fans; I am not the least bit elitist. The more the merrier! But attracting more fans cannot come at the expense of the game itself. 
Imagine how entertaining Baseball would be if runners could be forced out by hitting them with the ball. Of course, the very fabric of the sport would be forever altered, losing all historical perspective. But hey, it sure would be fun to watch! 
The unfortunate proposal to remove Off-Sides has reared its stupid head once again. This is a common and frequent suggestion, but without real insight. Remove Off-Sides and every match would result in one herd at one goalmouth and another herd at the other goalmouth, each fouling and slogging about for a garbage goal. The Off-Side rule is integral to the sport. Do not tamper with it. 
The only small modification I would make is to extend extra time, keeping the golden goal. In NCAA, two 15 minute halves is just not long enough. Make it an additional 45 minutes, with no intermission. Fatigue will set in and someone will eventually score. If still equal at the end of an additional 45 minutes, then call the regular season a draw, and call the post season PKs. Done.
