(MCT) — SOUTH BEND, Ind. — Before this season, Bennett Jackson had to do a report. Every Notre Dame defensive player had to. Bob Diaco, the defensive coordinator, assigned them, and the idea was to prod college kids to absorb and appreciate the struggles of someone they never met.

For Jackson, a junior cornerback, the subject was wrestling great Dan Gable. Gable’s sister was murdered in his family’s home in 1964. Jackson found that Gable moved into his sister’s room after the tragedy, a statement that the evil wouldn’t derail his life. He lost one match in his entire career at Iowa State and won a 1972 Olympic gold medal without surrendering a point.
