Two years ago, the Seattle Seahawks and New England Patriots made the decision to move on from Super Bowl-winning coaches Pete Carroll and Bill Belichick. Those decisions have been validated now that Mike Macdonald and Mike Vrabel have engineered quick turnarounds to get the two franchises back to the Super Bowl, with Macdonald doing it in his second season in Seattle and Vrabel in his first in New England. This marks just the fourth Super Bowl featuring two head coaches in their first or second year.
