In that situation Maul or ruck would happen, scrum probably and after scrumming open side flankers might have get some move and try , if my team wins and its play offs and dying minutes drop goal would be good to,
In Union like I said scrum are thougher, defense are tider and harder, you cant so easy move ball and run and get try, you can brake the line but not so easy, ball carrier has advantage but he is most hunted man then
