FILE - In this Tuesday, July 18, 2017, file photo, Baltimore Ravens lineman and math scholar John Urschel teaches a STEM lesson at Dundalk High School in Baltimore. Urschel is loving life after the NFL. It's been nearly two years since the offensive guard retired after just three seasons with the Baltimore Ravens. The 6-foot-3, 300-pound Canadian left millions of dollars on the table to pursue his two loves _ mathematics and time with his 16-month-old daughter, Joanna.
