Yahoo Sports reports: Add Norman Powell to the list of this past season's All-Stars who are changing addresses this summer in NBA free agency. Powell has agreed to a two-year deal that could be worth up to $45 million with the Chicago Bulls, a person with knowledge of the talks said Wednesday. Powell also had received some interest from the Detroit Pistons, said the person, who spoke to The Associated Press on condition of anonymity because the contract cannot be finalized until July 6 at the earliest.
