On June 13, 2011, the Bobcats hired former Portland Trail Blazers general manager Rich Cho for their own GM and promoted Rod Higgins to President of Basketball Operations. On the day of the 2011 NBA draft the Bobcats sent Stephen Jackson, Shaun Livingston, and the 19th overall pick to the Milwaukee Bucks. In return, the Bobcats received former Duke star Corey Maggette and the 7th overall pick. They used that pick to draft forward Bismack Biyombo and then drafted Kemba Walker, the NCAA Basketball Tournament Most Outstanding Player, with the 9th pick in the draft. They also traded their 2013 second-round draft pick to the Thunder for 7-footer Byron Mullens and signed sharpshooter Reggie Williams in free agency. The Bobcats started the 2011–12 season with a close 96–95 win against Stephen Jackson and the Milwaukee Bucks in their home opener but wins would be scarce after that. In the lockout-shortened season the Bobcats struggled and posted an NBA-worst record of 7–59, losing the last 23 games of the season. In a nationally televised game against the New York Knicks the Bobcats recorded yet another loss as their win rate dropped to 0.106, setting the record for the worst season by an NBA team (because the season was shortened by the lockout, the 1972–73 Philadelphia 76ers kept the record for most losses in a season, with 73). On April 30, 2012, the Bobcats announced that Silas would not return to the team for the 2012–13 season. St. John's assistant Mike Dunlap was named his successor.
