No, I didn't.
Yes, you clearly did because it renders your attachment and the point you were trying to make utterly irrelevant.
If a defender is stood in position when an attacker strikes the ball.....the ball hits the defender, who hasn’t made any attempt to play the ball (i.e. stood still) and it ‘deflects or rebounds’ to another attacker stood in an offside position......this is offside / gaining an advantage....
If the same defender tries to play the ball (play being defined in the LOTG as ‘Action by a player which makes contact with the ball’) and it hits their outstretched leg and goes to an attacker in an offside position......this is not offside, nor is it gaining an advantage.
In the OP the block by the defender is clearly playing the ball therefore no offside offence is committed.
