Damien Williams and Khalil Herbert step up in David Montgomery’s absence — and Justin Fields delivers a gutsy performance — to help the Chicago Bears find an identity on offense

“When you have a guy like David who is a run-hard kind of guy and he’s going to get those hard yards, that’s what everyone is expecting,” Williams said. “And me being who I am, that’s how I carry myself as well. We are going to go in here and get these hard yards and keep going. And (Herbert) had that same mentality.”
