As an opposition supporter from what I have seen of Mr Hirst, he was when Dewsbury were at their best in recent years not a stand out star. For a lad his size he didn't appear to be pulling his weight compared to some of outstanding players around him.
I would now say from the few games I have seen of Mr Hirst recently the improvement, work rate, commitment, positioning have hugely improved. He in my opinion deserves a Superleague consideration. Not sure he will shine as a superstar, but certainly hold his own, and maybe surprise a few.
