The NFL's owners and players continue to work on a timeline for transition rules, with teams feeling like they might need more than three days from the opening of facilities until the start of the league year and free agency. The teams will need to see 30 or more players in many cases to be ready for camp and also need time to digest rules, rework contracts and try to re-sign their own free agents. Timelines being discussed could include free agency possibly starting Sunday and training camps right around that time.
