3. The Lions have one of the best O-lines in football
The strongest aspect of the Chargers defense this year has arguably been the pass rush. I say "arguably" because I know the run defense has been very strong as well, however, the pass rush has really set up everything good for the Bolts this entire season.
How do you hide the weakness in the secondary? Get a strong pass rush going so the secondary won't have the time to be burned.
That's what the Chargers have done with, mainly, Khalil Mack (9 sacks/9 QB hits), Joey Bosa (6.5 sacks/8 QB hits), Tuli Tuipulotu (4 sacks/7 QB hits), and even Morgan Fox (5.5 sacks/8 QB hits) who's really gone under-the-radar amidst the big trio of outside rushers on this team.
My concern, though, is that the Lions have the best offensive line that the Chargers are going to see all season. I'd actually put them only behind the Eagles O-line at this point- they're that good.
The Lions, in turn, have only let up 16 sacks this season. That's with a pretty statuesque quarterback in Jared Goff behind center.
So, this meeting is going to wind up being a test of which unit is better between the Lions' stout offensive line and the Chargers' rapidly evolving defensive line.
This will be the difference when it comes to potentially halting this Lions offense- whoever wins this battle.
