I honestly can't recall the last time a D decisively shut down a half decent O, gave up less than 20 pts. and won the game on their own merit, those memories seem to be from a different era when teams relied more heavily on the running attack. The only recent examples I can think of is when a team is handicapped by inexperienced or pathetic QB play and spends the majority of the game going 2 and out and giving the ball away consistently, do those really count as staunch D victories? I'd like to see a D dominate a game to the point of winning it, but I won't believe it's a viable possibility until I do.
