‎"We are excited for these three icons to join our league," said Roger Mason Jr., BIG3 commissioner and president. "The addition of these greats and the outpouring of interest from our industry continues the incredible momentum and enthusiasm we've seen for the BIG3 since the league was announced."

Former NBA players who have committed to play ‎include Kenyon Martin, Jermaine O'Neal, Rashard Lewis, Jason Williams, Bonzi Wells, Mike Bibby, Ricky Davis, Al Harrington and ESPN analysts Chauncey Billups and Stephen Jackson.

The league plans to hold four games every Saturday from June 24 through Aug. 26 in a different arena and city throughout the country.

The league's structure also calls for coaches to be selected by player captains in a draft this spring.

Barry and Drexler are both members of the Naismith Memorial Basketball Hall of Fame and each won one NBA championship ring in their pro careers. Mahorn was a key member of the Detroit "Bad Boys" Pistons team that won an NBA title in 1989.
