When 80,000 fans pack MetLife Stadium each time the Giants and the Jets play this season, they are unlikely to notice the 22 new radio receivers placed discreetly around the building. Nor will they see the radio frequency chips embedded in every player’s shoulder pads.

But with this gear, fans watching on television and following on the Internet will be able to see how fast and far players are running, how far offensive players are from their defenders and other statistics and data-driven graphics.

Like Major League Baseball, the N.B.A. and other sports leagues, the N.F.L. is trying to feed the seemingly insatiable desire of hard-core fans for in-depth information about the game. The league has long made its statistics available to video game developers, fantasy football league providers and television broadcasters looking for new and more authentic ways to illustrate games.

But several years ago, the N.F.L. tried to find a way to track players more precisely during games, not unlike how the M.L.B. tracks every pitch and the N.B.A. uses cameras to catalog every play. After a technology bake-off, the league last year signed a deal with Zebra Technologies, which uses radio-frequency technology to help companies monitor their merchandise, fleets and other assets.
