In response to prolate0spheroid's comment:
This is partially true. I think there is a tendency to lump those two Superbowls together. One was all about the Giants Dline. The Pats offense really struggled to move the ball. McDaniels and BB couldn't adjust. The offensive line got beaten bad. Tom Brady was basically a punching bag ... Maroney was a zero.
But the second one was much more efficient. If you gave me those numbers by the offense over the course of a season (scoring percentage on drives, yardage, turnover rate) you are talking about a good offense. That they had so few opportunities to score with, is another story altogether.
Yes, the games were quite different, though there were still some commonalities. In SB 42, the Giants defensive line was the major issue for the Pats' offense. The Pats had some injuries on the O line, which may have exacerbated the problem, but that D line and the scheme employed (with three athletic pass rushers--Tuck, Osi, and Strahan) really stifled both the running game and the passing game. The Pats had much better and deeper receivers and runners in 42 than 46, but plays just couldn't develop because the Giants D line so dominated guys like Kaczur and a gimpy Neal. The Giants also had something like a nine minute drive to open the game . . . that was a hint at the defensive problems that were starting to emerge.
I think the major issue in 46 on offense was the injury to Gronk. We just didn't have enough other offensive weapons to compensate. I will say, however, that when I watched the coaching film of SB 46, I was surprised at the number of missed blocks in the running game. The O line did struggle a bit with the Giants' D line, though they weren't as completely dominated as they were in 42. As you say, the Pats were also not as bad as some seem to think on offense. They orchestrated two very good drives mid game. But they needed to be better on their other drives given how few they had because of the defense being unable to get the Giants off the field.
