Wrong...Gordon Hayward is under contract with the Utah Jazz until July 1, 2014.
According to
Wikipedia:
July moratorium
Players on a team's season-ending roster remain under contract with their respective team until the start of free agency on July 1.[32] During a period in the beginning of July, teams may begin negotiating with free agents, but trades cannot be made and most free agents cannot be signed. The salary cap for the upcoming year is not set until the league's audit is completed by the end of the period.
See above...Why can't a coach talk to his own player that is still under contract (and vice versa)?
