Steve Cram seems to be doing well with the curling, along with Jackie Lockhart. It can't be an easy sport to commentate on interestingly, but how surprising that Steve Cram has such an interest in curling! He has actually bothered to do some research on it too, so he makes some informative comments.
Unlike Hazel Irvine, who despite years of sports commentating, rarely says anything interesting on any subject. Jonathon Edwards does not impress me as he again seems to fall into the bland and boring style which presumably the BBC viewers prone to complain like. I thought the best commentary from him was after the speed skating when he handed over to the Dutch commentator, who talked at length in an erudite, interesting and fascinating way.
