LAC have played five games against top 10 scoring offenses this season and have allowed 29.6 ppg in those games. Those offenses averaged 31.4 ppg for the season, so they slowed them down to the tune of 1.8ppg.
This was the most important part of your post. The Patriots will score on these guys, particularly at home. I saw a team yesterday that was up 12-0 at the half and could not get the ball in the end zone, as much because they played conservative every step of the way. They settled for field goals.
I posted during the game that the Chargers were throwing the ball behind the line of scrimmage and almost never past the sticks. Rivers looked like he had trouble getting the ball downfield all day. That's a problem since he's throwing into a superior Patriots secondary to the one he faced in Baltimore. I agree the pass rush won't be as fierce, but the line exposed its weaknesses yesterday.
Their travel schedule seems ridiculous. Flying back to the coast for a couple of days and turning around and flying back to the East Coast is a waste of two days travel. The Patriots will better use that time.
Granted, that was the first Chargers game I watched closely all season, but I am unimpressed and mystified about how they got to 12 wins. They beat the the Raiders 2X, the Broncos, the 49ers, Bills, Browns, Bengals, Steelers, Cardinals, Titans, Seahawks, and Chiefs. They lost to the Ravens, Rams, Chiefs, Broncos. In other words, they went 2-3 against playoff teams while the Pats went 4-0.
