Ex-NFL super agent Joel Corry doesn't believe the Arizona Cardinals and running back David Johnson are destined for a prolonged holdout. The NFL Collective Bargaining Agreement states players cannot accrue a year towards free agency if they do not report to training camp less than 30 days before the regular season opener. Johnson would have to report to camp before August 7th to avoid becoming a restricted free agent opposed to an unstricted free agent at the end of next season
