The pair played together for a season-and-a-half on the Orlando Magic from 2009 to 2011.
Williams, 41, was one of the most exciting passers in NBA history, averaging 10.5 points and 5.9 assists per game over a career that included stops with the Sacramento Kings, Memphis Grizzlies, Miami Heat and the Magic.
Even after his career, he has continued to make appearances in pro-am competitions and hasn't lost his passing touch. The Big3 shared a Williams highlight reel on Twitter:
Yes, he's still the master of the flashy pass.
Lewis, meanwhile, carved out a niche for himself in the league as an excellent three-point marksman, finishing his career as a 38.6 percent shooter from beyond the arc. His 1,787 three-point buckets are the 12th-most in NBA history. He averaged 14.9 points and 5.2 rebounds per game in stints with the Seattle Supersonics, Magic, Washington Wizards and Heat.
He was also a two-time NBA All-Star, and as Ian Kenyon of Bleacher Report noted, Lewis likely would have fit perfectly in today's three-point heavy, floor-spacing league:
Certainly, Williams and Lewis will be expected to hook up for quite a few drive-and-kick three-point buckets. They should be a solid pair for the 3 Headed Monsters in the new league started by Ice Cube and former NBA player and NBPA deputy executive director Roger Mason Jr.
