Northwestern's Trevor Siemian said Wednesday it was wrong for former quarterback Kain Colter and other players to explore unionization without first taking their concerns to their coach and administrators. The school's football players are scheduled to vote later this month on whether to form a union to possibly bargain over better compensation, health insurance and work conditions. Siemian, a quarterback who will be a senior this fall, said during a conference call with reporters that players should have taken their concerns to coach Pat Fitzgerald and athletic director James Phillips before setting out to unionize.
