In the wake of the NFL player protests during the national anthem, we talk with Andrew Maraniss, the author of "Strong Inside," the story of Perry Wallace and breaking the color barrier at Vanderbilt in the 1960s. The issues which faced Wallace — and many of the names he was called just for being black — echo much of the criticism of NFL players. Maraniss also talks about the challenge of converting his book into something for middle schoolers to read, his Pulitzer-winning father and more.
