In the video above, ESPNBoston.com’s Mike Reiss gives his three keys to a Patriots victory over the Chargers on Sunday:
* Defending big plays in the passing game. Particularly with the Patriots thin at safety, this will be important to protect against.
* Pass protection. The Chargers rank second in the NFL with 21 sacks on the season. Patriots players say this is one of the faster defenses they’ll play this year.
* Coming out strong in the second half. San Diego has outscored opponents 46-14 in the third quarter of games this season. The Patriots solved their second-half road woes against Miami on the road a few weeks ago, can they start a new trend?
