That's not really the impression one gets reading the article. It says there is interest by the Bills, no real market for some of their free agents (meaning they can be had for at or near the minimum), and yet Nix stated they wouldn't be pursuing them until later in the summer or even early in the season. As the author points out, Nix seems to be suggesting they won't be making moves on any free agents until Byrd's deal is done. Rebuilding "via mid to low tier FA's" on the cheap is not really even hinted at there.
