I had Buffalo in several of my leagues, my two biggest in fact.
I just flat dropped them this week. I really have no concern if they get snagged, since their immediate schedule is bad plus the bye in week 10.
Also, I have brutal byes that week, so I knew weeks ago I was going to have to start preparing for that.
If I can I will try and snag them during their bye week, then play them rest-of-season.
I would like to get them back, but it won't be a disaster if I cant pick them back up, at least in my case....I think they are at the lower end of "must start".
I don't really keep defenses unless they are blockbuster plays week in and week out.
