I'm nervous about this game, the more so because it is so important (to both teams).
EJ seems to struggle against 3/4 Ds. Can't read the linebackers.
Though Texan's run D has been porous, they have so far also had to defend the pass too.
Facing EJ will be different, and easier, than facing RG3/Cousins, Eli or even Carr.
As someone said earlier, just follow the Chargers blueprint.
Take away EJs first read.and let the fun begin.
If you are not a threat to throw the ball more than 5 yards downfield, your run game will struggle.
