Yes, Muck posted this link in another thread but at the time it had not been fully updated to include all of the cuts that happened to get teams down to their 53 man roster. So this list as you post it now is basically the most comprehensive list of what players are available for grabbing, that have been cut from other teams.
If only it included players who were still unsigned like Ben Coleman, then it would be a complete list of all players available for signing.
