I noticed that on this website under Players, there are two sections, one called "Free Agents" and another called "Potential free agents".
I understand that the potential guys are players who's contract run out in February. The other list, which I have not noticed before seems to have players that became free agents this past february or were released this year. Is this how you understand it? Certianly not everyone that came to training camp is on this list, but many are (Did Nate Davis make it out of training camp this year?).
