Now that the draft is finally in the books, the real work for the front offices and agents around the NFL begins: the undrafted free agent frenzy.

Every year, each team usually nabs ten to fifteen players who didn't get drafted and gives them one final chance at the NFL. Most of these players don't make an impact, but some can blossom when they're given the chance to become stars.

The Buffalo Bills, of course, will be on the prowl for a few of these guys, and we'll do our best to keep track of who they end up signing. Keep in mind, all of these tweets (even the ones from the players themselves) are unofficial, since there's the matter of physicals and paperwork before they can officially be added to the roster.

Anyway, on to the list, which will be updated as signings are announced:
