There are a number of proposals that have been floated to fix pks. The biggest objection has been moving the spot back would require redesign of countless pitches including in some countries that can’t afford it. But there are some other proposals going from least intrusive to most:It's the nature of the rules that soccer is a lot more "all or nothing" in terms of the impact of individual calls. A PK may end up being the only goal scored in a game. That's quite a difference. Same with cards - two yellows, gone for the game. It's kind of painful when you consider how much more measured penalties are in other games in terms of the impact on the final score and it obviously affects how fouls are called - which leads to inconsistency.
The push in the back is one of the most inconsistently called fouls I see in youth soccer. It's the hockey equivalent to cross-checking but actually has a bigger impact in soccer. In hockey, at least you can use your legs to try to rebalance and use the stick to control the puck. In soccer, you need to balance and control the ball with your feet. I wish they'd call it every time. The game would still be sufficiently physical. If people want more physical, there's MMA.
-let the goalkeeper move on the whistle.
-prohibit long run ups to strike the ball
-dfks for most fouls inside the box except for flagrant ones like a dogso handball or foul to injure; pks for the flagrants.
-move the spot back
-change the scoring for 1 for a pk, 2 for a goal and add a three pointer for distance.
