That's a little revisionist and disingenuous. It's always tough to move the ball in the red zone because the field is condensed and there's less to defend and they were mostly the ones making the plays to get the the takeaways on defense (save for the ball off the helmet). And you can only go as far as the end zone on any drive so you shouldn't hold the starting position against them on those drives.

The fact is they were still outgaining the jags 170-50 when they went up 27-0, even with all those short fields limiting their potential to gain yards (16 and a 18 yard TD drives). If they were bad, what were the jags? They definitely weren't perfect, but calling them bad the whole game is pretty stupid. Jags also were aided by two big in-game injuries to the chargers that affected their second half (LT on offense and their best CB on defense).
