Jones specialized in quarterback "sacks", a term which he coined. Nicknamed "the Secretary of Defense", Jones is considered one of the greatest defensive players ever. The Los Angeles Times called Jones "Most Valuable Ram of All Time," and former Redskins head coach George Allen called him the "Greatest Defensive End of Modern Football." Jones was inducted into the National Football Hall of Fame in 1980.

This hardback copy of "Headslap" was signed in blue by Jones and inscribed, "HOF 80." This book includes a Great Moments COA.
