Johnson and Durkin

[my miss storm cat]

This is probably a really stupid question but why exactly does NBC use Durkin instead of Johnson?

No disrespect intended and I know he has a ton of fans but Durkin makes me want to slit my wrists.

Johnson? I could listen all day.

He's got that style where one could close their eyes and see the race. (A lot of the time anyway).

What do you all think and can anyone answer?
