The issue for the Chargers going forward is their defensive stars - Bosa, Mack and James are old. If they drop off this O needs a lot of work to be able to pick up the slack.
Their point was if you kick rather than sneak on 4th all you do is make it 2TDs plus 2 pointers. You don't make it a 3 score game. Therefore possession is worth more.
I think it is a bit of all of it. Herbert has shrunk, the weapons are poor and you can't lose up front when you have three first round picks on your OL.
He is statistically bad in the 3rd Quarter throughout his career. The classic Herbert game is getting too far down in the 3rd and falling just short of a heroic comeback in the 4th.
Roman's passing game is always limited but his run game is normally creative. It is like Harbaugh has told him the only run he is allowed to call is up the gut.
Houston have only called that one pass play all night. Presumably LA didn't defend it there because the law of averages was they must call another concept at some point?
