The Bills D is not quite the swiss cheese some in here are making it out to be. They allow 4.2 ypa, which is tied for 17th in the league. The 4th place team allows 3.8, the 28th allows 4.6, so they are firmly middle of the pack.
They have only allowed 8 rushing TDs, which is 9th best.
There is no doubt they have been bad the last two games. There are no injuries or player changes to account for this, so one might assume they were game planning to stop Ryan and make the Atl run game beat them (it did mainly with two very long TD runs) and game planning to stop Glennon and make the TB run game beat them (it did with an 80 yarder).
One might suppose that against a crappy Jax passing attack, missing it's two best WRs possibly, that they will load up to stop the run. If anything I would look to start ACE against a bad Bills secondary.
The Bills give up 124.8 ypg and Jax rushes for only 76.6 ypg, granted they are a little better their last three, with two putrid games if you make it the last five (2.0 ypa against Ari, 1.8 ypa against Ten).
This is probably desperation talk anyway, but if you are starting Todman look for a 40-50 yard, 0 TD floor with 120 yard, 1TD upside if he can break a long one.
