Roethlisberger did what great quarterbacks do -- with ~2 minutes to play, down by 3, he took the football and said "Mine." Both QBs played extremely well, which was a surprise given how well both defenses had been playing leading up to the Super Bowl.
Pittsburgh is the unquestioned class of the NFL. They play football their way, and their way has worked for the better part of 30 years.
They play hard, and the play tough. And, as a result, other teams play scared. It's why you see the Steelers delivering big hits instead of receiving them season after season.
