Without ceremony or even so much as notation, the end of the Super Bowl reliably launches the longest offseason in sports, a solid seven months between NFL games that matter.
Major League Baseball goes dark only five months, the NBA barely four, and as for hockey, the NHL's offseason and the Fourth of July weekend seem of the approximate same length.
But despite its relatively luxuriant downtime, the NFL can virtually guarantee you that the game will return in September with no more idea of what a catch is than it "possessed" last week, which was no idea whatsoever.
