What are your thoughts? How would it shape the future of the game tactically? Which style of play or manager would have the most success?
I would say that a high press system that relies on mitigating counter attacks by catching the opponent offside might suffer the most. For example - Ange’s high line defense against Chelsea in their 4-1 loss.
It wont solve anything. A better change would be no offside at all if ball is between 18yd line (extended across pitch) and end line. High line would still work, but you need to mark attackers inside the penalty area. This would get rid of a lot of the checks.
