The Seattle Seahawks are entering a new era under head coach Mike Macdonald, who takes over after Pete Carroll's departure following a lackluster season. Macdonald, at age 37, is the youngest coach in the NFL and has a reputation for defensive prowess, having previously coached in Baltimore. He emphasizes accountability within the team, demonstrated in training camp interactions where both players and coaches are held responsible for their actions. The Seahawks' roster boasts talent, including quarterback Geno Smith and skill players like DK Metcalf and Kenneth Walker III, while improvements to a struggling defense are a priority. The team is looking to revitalize its performance in the NFC West with new offensive and defensive systems in place. Overall, there is a cautious optimism among fans and analysts that Macdonald can lead the Seahawks back to competitiveness.
