The Toronto Raptors appear to have some competition for Lou Williams' services.

According to RealGM.com, Williams is expected to generate interest from the New York Knicks, Sacrament Kings, Brooklyn Nets, and Los Angeles Lakers as an unrestricted free agent this summer.

However, RealGM also reports that Williams and the Raptors have mutual interest in keeping the shooting guard in Toronto.  The two sides can negotiate exclusively until free agency opens on July 1.

Williams, 28, is entering his 11th season in the NBA. He has spent time with the Philadelphia 76ers, Atlanta Hawks, along with the Raptors.

Coming off an torn ACL in 2013, he enjoyed his more successful season in 2014-2015. He averaged a career-best 15.5 points per game and captured the NBA's Sixth Man of the Year award.
