Why the NFL's Field Goal Record Is Waiting to Be Smashed

Based on his data, Pfeifer says that a record-breaking 70-yard field goal kicked at sea level, with no wind, would require a foot speed of around 49 miles per hour delivered right to the ball’s sweet spot, while an 80-yarder would take a foot speed of about 56 mph.

According to the release put out by the Nevada Museum of Art, after the satellite was deployed it successfully established communication with ground stations on Earth, but the sheer number of satellites being deployed meant the Air Force was “unable to distinguish between [the satellites] and could not assign tracking numbers to many of them.” Without a NORAD tracking ID, the FCC wouldn’t give the okay to Paglen’s team to deploy the reflective balloon contained in the satellite.

But also: If Nash can show up unpracticed, four years after retirement, and drain 98 percent of his free throws in an impromptu shootout against a ham-handed journalist, what kept him from shooting that reliably during his career. Surprisingly, Silverberg says there's very little separating players like Nash from those who average 75 percent from the line.
