We already have a video from Wealey which shows Smith being stumped like that. I am not sure if @MattW has been able to replicate this yet but it would be good to have a video of a human getting out in the same fashion. I am going to try and do the same next time I play.
I have over 100 hours on Ashes. That Smith stumping was the only stumping I have.
I'm genuinely shocked if you had 5 in one innings?!quoted wrong person
