They have to change the sanction for an accidental handball, they can't go on giving penalties for this. Make it an indirect free kick for anything other than deliberate goal saving handballs (the old kind of handball) and we can move on with our lives.
But they should be objective to the striker, he's trying to stay onside by the law which says level is onside. If he has to think about his toe or shoulder being marginally ahead of the defender then strikers have to relearn the game
Offsides should be easy. Just create a definition of 'level' - overlapping torsos or whatever, and then apply 'linesmans call' to that. He flags him off, he has to be off by a mm or whatever to overturn it. He doesnt flag, then he stays onside provided the 'level' definition is met.
