I'm not saying the Bills wont look into Boss Bailey. Odds are they already have. But his injury will scare them off, methinks. I dont see the Bills going into the season with the OLBs they have, they will add a vet before/during training camp to compete.
One other thing to note is that Jauron is VERY familiar with Bailey. Coached against him, then had him as a player for a couple of years when Jauron was a DC and HC with Detroit.
