The NFL Lockout is still in place. Players can't use team facilities, coaches and players can't have contact, no "official" organized team activities can take place. Players from teams around the league have begun organizing their own group workouts, however, and the New York Giants and New York Jets have both joined those ranks.
Really, this is about all teams can do at this point in terms of getting in any type of organized work. No coaches, no playbooks, just players getting together and working out in groups on their own. At least it's something, but it certainly is not ideal.
