Dr. Priya Narasimhan, a professor at Carnegie Mellon University, doesn't intend to put a single NFL referee out of work, but there's no doubt that the technology she's tinkering with could indeed have that effect. The prof and her students are developing sensor-laden footballs and gloves, both of which could eventually tell in real-time whether a ball bounced off the ground before being caught or whether a player actually had possession of a ball whilst being piled upon after a fumble. Currently, she's had zero luck persuading a college or professional team to help her experiment further, and we can sort of see why. We mean, it's nice to get every call right in theory, but what fun would sport be without the all-important "Ref, you suck!" chant?
