1)Keep the damn time on the scoreboard clock. I mean really.
2)Replace the ridiculous penalty shot shootouts with a seven on seven overtime.
3)Get rid of penalty shots altogether. Replace with hockey style time in the penalty box.
4)Experiment with replacing the throw in with a kick in. (Pele's suggestion).
5)Replace the stupid group and knockout system with a seven round Swiss System tournament. This could eliminate the need to play off ties. Each team plays seven games and winner has highest score after seven rounds.
