If you don't know FIFA has been working on a technology that tracks the players including their limbs to help automate the offside process with var. Which means the VAR will no longer have to draw the lines it will all be done automatically and it is now being tested at the club World Cup with the goal of having it in use for the World Cup this fall.
Here's an example of it being used in today's game. What took me by surprise is how impressive the graphics package is. It's basically created a goal line technology style animation that shows exactly which part of the attackers body was offside and gives a nice side angle view. It should help cut down on those examples where we're trying to track the line coming from the defender shoulder and seeing where the attacker is and everyone being confused.
