Macdonald set to become NFL’s youngest head coach at 36 as Seahawks swoop

• 36-year-old ran Baltimore's league-leading defense
• Macdonald agrees to six-year contract to replace Pete Carroll

The Seattle Seahawks are hiring Baltimore Ravens defensive coordinator Mike Macdonald as their new head coach, according to multiple reports.

Macdonald, 36, will become the youngest current head coach in the league and is half the age of the man he's replacing - Pete Carroll, who moved to an advisory role with the organization after 14 seasons in charge in Seattle.
