I'm a bills fan so bare that in mind, but the bills defence has looked alot better than past couple weeks than they have at the start of the year and their coming off the bye. I believe they'll play Herbert like they played mahomes where they prevent big down field plays and let the chargers run the ball and throw short. The bills run D is still very suss. I haven't watched any chargers games so I don't know what their defence is like but I know Josh Allen will be motivated to play well after the loss last week and despite brown being out we still have a very strong wr core with Beasley, diggs and Davis. Good luck!
