If freeway traffic gets bad enough, does it actually move backward? We could find out this NFL season when, in the rarest of scheduling rarities, the Rams and Chargers will play simultaneous home games at the Coliseum and StubHub Center, respectively. That hasn’t happened in the same market since before 1983, when the New York Giants and Jets began sharing a stadium (unless you clump the San Francisco 49ers and Oakland Raiders in the same Bay Area market.) Regardless, the competing Rams and Chargers games lend new meaning to the mantra “Fight for L.A.” and take place in Week 2 (Washington Redskins at Rams, Miami Dolphins at Chargers), Week 14 (Philadelphia Eagles at Rams, Redskins at Chargers) and Week 17 (49ers at Rams, Raiders at Chargers). The NFL won’t always have the luxury of that particular scheduling quirk. The Rams and Chargers will eventually share a stadium in Inglewood that’s expected to be completed for the 2019 season. That’s when scheduling will get even trickier. “Truth be told, this is as easy as it’s going to get for us,” said Michael North, the NFL’s senior director of broadcasting. “Because as soon as they start sharing a stadium, they’re the Jets and Giants, and obviously only one can be at home each day.”
