I don't know about the task being tougher. The defense didn't have a great night but it is worlds better than any of the Pats defenses since about 2004. Denver won it all in 2015 with a corpse at QB. Their D played other worldly, that is kind of the blueprint. They did have a better running game though.
Bottom line is you can't throw picks on your own 20 yard line and give up free TDs. The Pats may very well have still lost last night but this team can't afford those types of mistakes.
