With Trail Blazers owner Paul Allen in attendance, Justin Jackson works out for Portland Posted Jun 21, 2017 The most telling part of Justin Jackson's predraft workout with the Portland Trail Blazers had nothing to do with his shot missing the mark. Blazers owner Paul Allen and vice chairman Bert Kolde were courtside to watch Jackson in a group workout. That Allen was in the building is an indicator that the franchise and its owner had special interest in the final group. (Oregon Live)
