Yes, it may be the defenses' job to stop them, but when it's the fourth quarter and you've spent 3/4 of the game on the field running all over the field trying to keep up with New England's receivers (and are dead tired from doing so), and they're STILL throwing it down the field, how are they supposed to stop them? They got them into a 4th down and relatively decent yardage and New England went for it anyway. I don't care whether it's the defenses' job to stop the offense or not, the only reason the Patriots are doing this is for humiliation purposes, and that's beyond necessary. How did it feel to anyone when Kansas scored that last touchdown on us? I guarantee no one on this site liked it. I don't care whether it's the pros or not - sportsmanship transcends all levels.
Personally, I'm going to feel very little sympathy for anyone associated with New England, be it the fans or anyone else in the organization, when either Brady or Moss ends up with a season/career ending injury while running up the score in garbage time, or 10 years from now when the Patriots are once again the doormats in their division and everyone is taking it to them (and in this scenario there had better not be a peep from a soul in New England about the sportsmanship of opponents running the score up against them).
