While I also hated the coverage, you have to understand who their target audience is. It is not Lets' Run die hard hardcore fans. 99% of the people watching this today have no idea who Kipchoge or Bekele is. And that 99% is the people who pay the bills watching the commercials from the sponsors and NBC.
The coverage was pretty much spot on for the needs and taste of 99% of the TV audience, and that sucks for us the 1%.
There's no-one watching this. Who the hell would watch NBC at this time on a Sunday morning?
