Ready for the Super Bowl?

The Kansas City Chiefs meet the Philadelphia Eagles in New Orleans for Super Bowl LIX tonight, and it’s likely that more than 100 million people will tune in. For many, it will be the only football game they watch this year.

If you’re among that group, good news: This is an ideal matchup for casual fans. For one, it’s a rematch. Philadelphia and Kansas City played each other in the Super Bowl just two years ago, and plenty of familiar characters will return. Patrick Mahomes and Travis Kelce are back. Kelce’s girlfriend, Taylor Swift, will probably be there, too.

And there’s history at stake. Kansas City is trying to win its third straight Super Bowl, which no team — not even Tom Brady’s New England Patriots dynasty — has ever done.

In the rest of today’s newsletter, we’ve got a guide to the Super Bowl, with contributions from my colleagues around The Times.

The teams

One thing to know about Philadelphia: The Eagles have pioneered a play called the “tush push,” in which players line up behind the quarterback Jalen Hurts and shove him forward to gain a yard or two. When the Eagles ran the play this season, it worked more than 80 percent of the time, according to The Ringer. But that’s no guarantee it will work during the Super Bowl. As The Ringer notes, Kansas City shut down several tush pushes by the Buffalo Bills during the A.F.C. championship game.

One thing to know about Kansas City: The team was 15-2 this season, but it won 11 of those victories, plus another in the playoffs, by a single score (meaning eight points or fewer). It won 17 straight one-score games, an N.F.L. record. The Athletic’s Mike Sando calculated that the odds of such a streak are about one-tenth of 1 percent. Is that a sign that Kansas City is lucky — or just great in clutch moments?
