Your team scores a big touchdown. Time to stretch your legs, grab a snack, maybe chat with a friend about the game. Anything but watch the extra point, one of the most anticlimactic plays in sports.
Extra points have for decades been pretty much a sure thing in the N.F.L. The success rate has hovered around 99 percent for 20 years. You have to go back to the World War II era to find rates below 90 percent.
Last season, teams tried an extra point 1,230 times. They missed only 8, for a 99.
