Improved? Kinda. But Scarlett definitely can fill the role Lawson had in Miami so I think its a wash and McKinney is a better player than Lawson and might be our Best LB if healthy. Van Ginkel outplayed Van Noy and will be starting in his place this year so yeah that's an upgrade. I think there's a better way to ask this question. Did we lose anyone we haven't replaced in one of the NFL's best defenses? I can't think of a single player we lost that makes us worse.
