This goes to the off-field person who contributed the most to their team's on-field success. Believe it or not, two Bruins have won this Award. There really doesn't need to be a list of nominees for this Award, because we know who's going to win it.
It's Bill Belichick.
This guy traded Randy Moss in the middle of a season, then won 11 of 12 games. This guy was the head coach, the offensive coordinator, and the defensive coordinator. He's developed a young defense into a ball hawking group of playmakers. He's engineered an offense that's scored the most points in the NFL, nearly 5 more per game than any other team.
The guy simply gets things done.
