As credible speculation continues to mount that the Buffalo Bills are contemplating trading up in the 2012 NFL Draft - perhaps with more than one target in mind - GM Buddy Nix has done what he can this morning to toss a proverbial bucket of cold water on those discussions.

A league source tells Mark Gaughan of The Buffalo News that the Bills' interest in Matt Kalil is "legitimate," lending credence to a Charley Casserly report that the Bills are willing to part with a second-round pick to move up for the USC left tackle. At the same time, Chris Brown of BuffaloBills.com speculates that the Bills could be willing to trade up as high as the No. 5 overall pick. Brown also believes that the Bills see Alabama safety Mark Barron as a "once-in-a-generation safety," and may be willing to trade up a bit to take him, as well.

Nix, however, was his usual to-the-point self in addressing the idea of trading up from a philosophical standpoint while visiting with WGR 550 this morning.

"If there's a guy there that you don't think you can live without - that he's a guy that's gonna be, for ten years, is gonna be a difference-maker barring injury - then you'd move up," Nix said. "If you look at this year's draft... that guy's probably not there."
