Whilst I agree with your comments in general about not using his physical attributes enough, I do wonder if that particular incident was a foul. I think the image below from the Bristol Post is the same incident from a better angle, which shows a tug of the shirt and would explain why he fell down so easily. Unfortunately, a clever foul as no official would be able to see the shirt pull.
