Williamson thinking of ’41 games at the Garden’

Jon Gruden and the Raiders traded Khalil Mack because they didn’t want to give a defensive player quarterback money. Now with the Bears, Mack is altering games in ways that some quarterbacks can’t. Which is putting Chicago’s quarterback, and the offense he is running, in a situation that they are perhaps not ready for: contention. Through three games, Mack has proved to be every bit the game-wrecker the Bears expected when they gave him a six-year, $141 million extension.
