Every sports commentator gets things wrong and if you take Clarkes Wigan bias out of the equation, he's a knowledgeable bloke.
Everyone seemed to rip Stevo and Hemmings apart but, considering how often they did the commentary and how long they had been doing it, they were pretty good.
RL suffers because it's a low budget sport, without adequate resource to really make a vibrant program and especially as its on the box 3/4 times a week.
Even well renowned pundits, like Murray Walker in Motor Sport or, Alan Hansen in football make mistakes and struggle to keep it fresh, although neither are commentating now, but, some folk expect miracles.
I'd still take Clark ove Jonathan Davies's commentary/ comment all day long.
