I'm in the group that says when you are putting the game away, keep doing it because stranger things have happened. I will never forget the Eagles Miami game where Miami came back behind 3+ TD's in the fourth to win all because the Eagles did what was "honorable" and tried to run the time out. Beat em till their dead so that you keep the game under control.
I also like the quote from the coach (can't remeber which one. but I think it was Bilicheck the year before last) that said "coach, why didn't you pull your starters with 4 minutes left and the game in hand?" His response, "they didn't pull theirs." Don't try your azz off Brooking, and get mad when they're still beating you. Get off of the field and show you've conceded if you want them to take it easy on you.
Further, I don't begrudge anyone that wants to go for any sort of NFL record either... If you can do it, go for it!
