Eh, you can't just look at the box score and say that. The Patriots are attacking them as they should, immediately passing to WR's on the line after the snap and barely running the ball. Even some hurry-up at times to keep them off-balance. They're not giving the Lions front 7 any chance to make plays.
Plus, it's in New England and these type of "showings" from opponents usually take place.
I mean that's fine but an elite defense should show up no matter the opponent. They were getting chewed up in the first half.
