I have seen Allison referee once and he gave a calm, focussed and very creditable performance.
From February 2017:
"Mr Allison's distinctive feature is what Michel Quoist in one of his more eccentric prayers described as "a fine dome," though it does not quite match Uriah Rennie's for the brilliance of its sheen. That apart, he went about his business in an unspectacular manner. Indeed, if we except the good movement, his alertness to both possible flashpoints and timewasting tactics, his excellent use of words in the ear on the hoof, his appropriate use of cards, his generally sound decision-making (hoppers' views discounted) and the way he appeared comfortable throughout in his control, then there is nothing special to enthuse over. It would be a very harsh observer, however, who was not happy with that particular list of accomplishments.
At this stage of the competition last year, Mr Allison was assistant at Hereford to a first-season 2A who was the only one of the four Q-F referees to be promoted to Level 1. Now 2A himself, he might tempt one to wonder whether history might repeat itself. It is not beyond the bounds of possibility on this showing."
I would be more than happy to see him promoted, though as Mackem says, it is still paper talk. There are however many referees among the 2A brigade whom I have seen put in excellent performances, so competition is very tight.
