After the news broke, another media person was talking about how he liked that Black would describe the game as if he was talking to someone who never saw the game before. Which sounds like a good idea on the surface. But it just isn't. Most of the people watching know the game, add in the fact that he continued to get basic things wrong and it just made things bush league.
You don't need to talk to people like they've never seen the game (literally no other league does this, not even obscure games like the AFL). You need to be passionate and knowledgeable.
