During the 2010 off-season, the Blazers' front office experienced significant personnel changes beginning in July with the announcement of new general manager Rich Cho, succeeding former general manager Kevin Pritchard, who was relieved of his duties after the 2010 NBA draft. Cho became the first general manager of Asian descent in NBA history. On August 12, the Trail Blazers signed two new assistant general managers, Bill Branch and Steve Rosenberry. Branch and Rosenberry replaced former assistant general manager Tom Penn, who was released by Portland in March. The organization also made changes to Nate McMillan's coaching staff by hiring Bernie Bickerstaff, Bob Ociepka and Buck Williams, with Bickerstaff assuming the lead assistant coach position due to the departure of Monty Williams. The Blazers acquired rookies Armon Johnson, Luke Babbitt, and Elliot Williams from the 2010 NBA draft and off-season trades. On July 21, Wesley Matthews signed a five-year deal with the Blazers after his former team, the Utah Jazz, declined to match Portland's offer.
