During most NFL offseasons, you can usually determine the depth chart immediately after the draft.

Teams haven't been given the chance to sign free agents yet, so most rosters currently consist of 2010 players plus the draft picks. Some teams added a player or two during the brief signing period a couple months ago (see: Redskins sign OJ Atogwe), but for the most part not much has changed.
