I don't know if I'm in the minority but I'm actually pretty happy with the Bills' moves so far. It looks like they are getting rid of players who's play doesn't match their contracts and it seems like they have been careful not to overspend too much in FA. The analysts are saying the draft is so deep at CB/S that teams will be able to find potential starters in the 3rd/4th rounds so it's not out of the realm of possibility that the Bills walk away with two starters at DB in the draft.
2017 might be a rough year because the Bills won't be able to replace Gilmore, Woods, Brown, AW, Graham, Alexander, & Robey in one offseason. But when you look at how the team performed last year, factor in a much tougher schedule this year, a terrible salary cap situation, and a 1st year head coach with new systems to install, it's unlikely 2017 was going to be a great year anyway.
Now the Bills have this year and next year to figure out their QB situation, and as long as they don't go out and spend a lot during the rest of FA, it looks like they could have as much as $70mil+ to spend in FA next year. This team has been kicking some cap problems down the road for a few years now, and this year seems like as good a year as any to get them all out of the way. Maybe that means the team is taking a step backward right now but hopefully it allows them to take three steps forward next year. (And hopefully the team is paying attention to compensatory picks and we're able to get extra 3rd & 4th round picks next year too)
