Winter Storm Jupiter might prompt some lasting changes in the National Football League. Adam Schefter of ESPN reports that moving the Pittsburgh Steelers at Kansas City Chiefs divisional playoff game from its original 1:05 p.m. start time to 8:20 p.m. ET because of Jupiter’s presence in the Kansas City area is going to be closely scrutinized by the league. Schefter’s league source says that the later broadcast could draw an additional 10 million viewers. That boost would be not only welcome but timely for a league that has struggled to maintain its once robust television ratings. There is a potential obstacle to making Sunday night playoff games an annual event, however.
