5-man mechanic for swinging gate

[MRH]

We open this Friday with a team we've had the previous 2 years and they always use the swinging gate for a try. The majority of the line lines up to the left and their kicker is right-footed which means the majority of the players are in front of the wing official who has vacated his position to be under the goal post with the BJ.

My concern is a) making sure there are 7 players on the LOS which could be missed without the wing official in place and b) if K chooses to run wide to the strong side I (R) may not be able to get to the sideline in time to cover it.

Wondering how your crews have handled this.

Thanks.
