Defensive lineman Calais Campbell is four games into his 18th NFL season and still playing at a high level. Craig Grialou, Paul Calvisi, and former Cardinals linebacker Lorenzo Alexander break down Campbell’s early impact, including his three sacks and four tackles for loss. They also discuss the team’s sixth-ranked scoring defense, what the offense needs to improve, and how Marvin Harrison Jr. is building momentum after a strong fourth quarter against the Seahawks last week.
