Every year after the Super Bowl, whichever network broadcasts that biggest of all big games also gets to use the time slot immediately after the post-game show as a launching pad, either unveiling a new series or rewarding an existing one. This year, NBC does the latter, by following Super Bowl LII with a new episode of its most popular current drama series, This is Us. There’s a tie-in, because the episode is titled “Super Bowl Sunday,” and features flashback sequences in which Jack Pearson (Milo Ventimiglia) and family gather to watch the 1998 Super Bowl. But 20 years ago, as previous episodes already have hinted, tragedy is about to strike, and all indications are that one of the members of the family is about to meet a very untimely death – untimely even in flashback. And if I were playing a game of Clue, I’d call it as Jack, in the kitchen, with a crock-pot. Time approximate.
