The Seattle Seahawks have hired Baltimore Ravens defensive coordinator Mike Macdonald as their new head coach. It remains to be seen if Macdonald can replicate the success of Pete Carroll, but his profile should have fans excited. The Seahawks ranked poorly defensively last season, so Macdonald's expertise will be crucial in improving their performance, especially against division rivals like the Rams and 49ers. If he can boost the defense, Seattle has a good chance of making the playoffs next season.
