Spurs swingman Richard Jefferson has opted out of the final year of his contract and will become a free agent. Spurs spokesman Tom James said the nine-year veteran informed the team Thursday. Jefferson was due to make about $15 million next year after underachieving in his first season in San Antonio. Jefferson averaged 12.3 points last season, his lowest since his rookie year. He struggled to adapt to coach Gregg Popovich's system, at one point losing his job in the starting lineup. The Spurs traded for Jefferson and his hefty contract last summer in a deal with Milwaukee.
