Well, I went to Google news and typed in Patriots and this article came up: http://www.philly.com/philly/news/breaking/20091020_Morning_Report__Patriots_really_ran_it_up.html
If you go to around the middle of the article you will see that the writer brings up Spygate claiming the Patriots "ran it up" to get revenge on Jeff Fisher for comments on Spygate.
Well, let us not forget that Spygate happened several years ago and people like to attribute the undefeated regular season to Spygate and can claim it was a fluke—remember the Patriots were caught before the season was even close to being 1/5 through?
This writer has a case of "Raiders beat us, lets rant on the Pats." Spygate is over (though I bring it up so oxymoron there) and it should left alone. The Patriots won because they are a professional football team that was better against the Titans.
Now to running up the score...
GET OVER IT NOW. People are paid millions to play the game and perform, the Titans did not and the Patriots clearly out classed them on that day. Patriots had a distinct advantage in that game—they are used to the cold, home field, and they have a fantastic team overall.
Running up the score would have been leaving Tom Brady in the game and throwing even more touchdowns in the second half.
Putting a back up in and going for it on a fourth down should not be shunned. If they went for a field goal then it would immediately have been an easy score and that would be running it up in my opinion.
Why did they throw so much though?
Well, half of their running backs are injured, why injure more? Pass was working, keep it going.
