Backup guard Shannon Brown has opted to terminate his contract with the Lakers and will become a free agent tonight at 9:01 p.m., agent Mark Bartelstein said. Brown hopes to re-sign with the Lakers. He was due to make a little more than $2 million in 2010-11, but hopes to get a significant raise over more seasons. “No question he wants to remain with the Lakers,” Bartelstein said. “Last year, he was offered more by a bunch of teams, but he wanted to stick with the Lakers. The Lakers knew all along this was the plan.”
