Right, they're good for the occasional broadcast and highlight. But anyone going to them for anything more hard-hitting than "So, LeBron, do you still bite your nails?" is going to be sorely disappointed.
Like someone mentioned above, the dichotomy at ESPN's production offices are between the Sports people and the Entertainment/Ratings people. And it's the same thing at news networks, other sports networks, whatever. And the Entertainment/Ratings people always win. They're concerned with selling a product, not honestly covering anything. Sports, news, soap operas, sitcoms, it doesn't matter: It's just viewed as a way to sell cars, beer, tires, diapers and ED pills.
