For the late night games you figure that the West and Mountain time stations are good with it, and most of the Nexstar and Sinclair CW base is pre-empting filler like True Crime News and The National Desk, and had enough time to bump their local coverage to their MyNet sister or to the DT2 subchannel.
As for the Fox stations it can only really help their coverage since they don't have to rush footage and pack editing suites to get their entire segment done, so it gives everything more time to breathe, and worse comes to worse, any pre-emptions have a full two days in overnights to be covered. And for Fox's O&Os they've begun to push their late newscasts to Fox Local on-time and a replay after the game, so at least for them there's no extra pain or having to wait until midnight to get on-air. For other groups with sister stations, things like "First on Fox" and "Most Wanted" aren't aired and the Big Three newscast is repeated late, or centralcasters like Coastal had the show well done outside weather before the game even started.
The thing I don't get though is why Fox hasn't killed the Saturday late night hour. No SNL rival is oncoming and you can't keep justifying a reality show repeat these days in that slot. And they might as well put Weekend Marketplace out of its misery already because the little money it makes when it does air can't even be a lot these days.
