Traditionally, there are two roles in sports commentary: the everyman and the expert. The everyman is Joe Average, a commentator who might not have a detailed knoweldge of the sport, but is pointman for the whole show. James Allen and Jonathon Legard were previously the everyman in the commentary team. One of the reasons why they were so derided during their tenures is because the everyman has to keep talking. You can't have periods of dead air. And you don't get to think about it the way you do print journalism. If you read James Allen's blog and see some of the pre-recorded stuff he's doing for One HD in Australia, he's actually really good. I was very impressed with his commentary duing Friday practice in Melbourne because he had the right balance of content for newcomers and old hands alike. The other role is the expert, usually a former competitor (or, very occasionally, a coach) who can provide insight into how the sport runs. You don't want to over-use the expert too much, because then you risk isolating newcomers to the sport. Martin Brundle has traditionally been the expert, but now Coulthard is filling that role. One HD interviewed Brundle and Coulthard about their new roles, and Brundle said that when Legard was dropped from the commentary line-up, he didn't really consider stepping up to the lead comentator position to begin with. Then he considered that it had been fifteen years since he had raced, and that he hasn't actually driven over 40% of the circuits (Bahrain, Malaysia, China, Turkey, Valencia, Singapore, Yeongam, Greater Noida and Abu Dhabi), so while he's got the knowledge of Formula 1, he doesn't have the most recent knowledge the way Coulthard does. And it helps that they've both raced and worked together, so they know one another. I think Brundle is the perfect pointman for the commentary position: he's a former player, but he's been commentating long enough to be able to fill the everyman role. I admit I was initially concerned about having Brundle and Coulthard commentating together since they were both experts, but one hour of qualifying was enough to prove the BBC has got one of the best Formula 1 lineups in years. Now, if only there was a way to mute the One HD "commentators". Every time they come back from a commercial break, they offer their thoughts on what is happening. Well, we don't care what they think because what they think is rubbish. Every last one of them is an everyman, but they all keep trying to make out that they're experts. They not as bad as the days of Eddie Everywhere, but they're not much better.
