It's Super Bowl weekend — so today's episode is all about football. First, a 2021 interview between NPR's A Martinez and former NFL wide receiver Keyshawn Johnson. Johnson's book The Forgotten First looks back at the racial politics of his beloved sport, and highlights four key players who desegregated the game back in the 1940s. Then, NPR's David Greene paid a visit to legendary coach Bill Parcells' home in 2015 and asked about his memoir, Parcells: A Football Life, and the coaching tree he left behind even after his retirement.
