I'm going to need an explanation as for why this isn't offside on Rashford. I get that he didn't touch the ball but why does that matter? He's clearly involved in the play, the pass was to him and him alone, and he runs alongside the ball for 15 yards. In the instances where an attacker is in an offside position standing between the goalie and the guy taking the shot, they still call that offside if the offside guy is obstructing the view of the goalie even if he never touches the ball.
