FILE - Baltimore Ravens lineman and math scholar John Urschel, left, hands out ice cream to Chelsy Valerio, 14, of Baltimore, during a lesson at Dundalk High School during the launch of Texas Instruments' STEM Behind Cool Careers series in Baltimore, in this Tuesday, July 18, 2017, file photo. John Urschel has found that a master's degree in mathematics, his stature as an accomplished author and his pending PhD at MIT isn't necessarily enough to sell young students on the benefit of crunching numbers. What really makes him interesting to most kids is that he's a former NFL player who opted to immerse himself in math. (Steve Ruark/AP Images for Texas Instruments, File)
