I think both coaches are outstanding and their record speaks for itself.
Belichick's decade-long run in NE and success as a DC with the Giants is legendary. However, it is equally fair to point out Belichick's 42-58 (1-1 playoffs) record as a head coach and five losing seasons out of six without Tom Brady as his starting QB.
Coughlin likewise has five losing seasons in 16 seasons, exactly the same as Belichick, but he took an expansion team to the AFC championship in his second season, and now competes in the far more rugged NFC East.
What I find interesting is how apparently little the media does in critiquing coaching decisions. Why is there praise for Belichick allowing the Giants to score with 1:00 left, but very little if any criticism for not making that decision one play earlier? The media manages to find praise for allowing the TD, but somehow isn't able to see it would have been far more brilliant to make the same decision one play earlier, thereby saving another timeout.
Likewise, why are few in the media critical of the ridiculous challenge of a clear Manningham catch, no matter how many yards it was.
If Belichick declines to challenge and allows the Giants a TD on their first, rather than second, try, the Patriots would have had three timeouts and more than a minute left to attempt a game-winning TD drive. His decisions directly cost two timeouts and approximately six fewer seconds of remaining game time.
Belichick deserves his "genius" praise from the media, from his defensive game plan against the Bills and 49ers to his intentional safety at Denver, etc., but I believe most coaches would be under far more scrutiny than he seems to have gotten for his poor challenge and clock management in SB XLVI.
