The most likely positions to be added are an inside line backer, offensive tackle, and the outside chance of a guard or tight end.We now have 20 undrafted rookies and nine drafted rookies on the roster.  The addition of two more rookies is highly unlikely. The two spots are likely to be filled by veteran free agents. These guys are most likely to be of a certain group of players.  Training camp is coming up and guys are going to get cut and buffalo is in prime position to grab a couple of okay stop gap type players. Nix has been dropping clues to how he free agency will go

Nix has mentioned keeping an eye on the waiver wire three times in the last week. It makes one wonder if there are a couple of specific players out there that he anticipates shaking loose from another roster. When asked if he did not intend to add another linebacker to his roster he wouldn't shut that door.

The problem is trying to predict who will get cut.  Channing Crowder got cut from Miami to make room for Kevin burnett.Nick Barnett is another possible addition ,but he is supposedly close to a deal with Detroit.  Green Bay  drafted two tight ends so it is possible one gets cut from there.  Who do you guys think will possibly bet cut in the next week.
