Generalizations here, folks. They're not 100 percent true, but they are based on my time in the biz.
Sports folks are more likely to be well-rounded. Yes, we sometimes listen to the 6 p.m. news outside of the two-minute sportscast. That stuff about the House of Representatives, the Senate, the car crashes, everything, we hear about it.
The news folks usually stick to their little fiefdoms. If you had a cops reporter and needed him to cover City Hall, odds are he'd be totally lost. He is focused only on his cops stuff, and he doesn't keep up with everything else.
Put a sports guy on a news desk, and he can flourish (and crank out pages faster than most of the news folks). Other way around, not so much.
