With Andre Roberson out for the season with an injury, the Oklahoma City Thunder are in desperate need of some help on the defensive end of the court. Because of this need, the Thunder and the Chicago Bulls have reportedly talked about a trade involving veteran guard Tony Allen. According to K.C. Johnson of the Chicago Tribune, the Bulls have talked to the Thunder about a potential trade involving Allen. Chicago recently acquired Allen as part of the Nikola Mirotic trade with the Pelicans and were rumored to be buying him out but could now be possibly trading him instead.
