The Philadelphia Eagles promoted Brian Johnson to be their new offensive coordinator on Tuesday morning, and now they have hired a defensive coordinator: Seattle Seahawks associate head coach Sean Desai.

The Eagles made the move official Tuesday afternoon after it was earlier reported by ESPN's Jeremy Fowler and Dan Graziano that a deal was close.

The Eagles lost previous defensive coordinator Jonathan Gannon to the Arizona Cardinals this offseason. Gannon, who coordinated Philly's amazing regular-season defense, will now be the head coach in Arizona. That move, along with Shane Steichen leaving for the Indianapolis Colts, gutted the coaching staff of the reigning NFC champions.

Desai will be coaching an Eagles crew that is loaded with playmakers at nearly every position. Their defensive line is stacked with talented edge rushers and a budding star in Jordan Davis. The same holds for their linebacker and secondary positions. Philly needs a coordinator who can make them a consistent threat week after week.

The Eagles' defense looked dominant before their Super Bowl loss against the Kansas City Chiefs. Unfortunately, the biggest reason for their loss was their inability to slow down KC's offense when it mattered the most. Giving up back-to-back touchdowns on identical plays was simply unacceptable. Here's to hoping Desai will lead this talented defense forward and help them get back to the Super Bowl and perhaps finish the job next season.

Desai spent last season on Pete Carroll's Seahawks staff after extended time with the Chicago Bears.
