The BIG3 professional basketball league opened for business today at the Barclay Center in Brooklyn.

Former Sixers star Allen Iverson is the player-coach for the 3's Company team.

The league rules have the first team to 60 points winning the game and you must win by two. There are two's, three's and a four-point shot, which are located on three areas of the floor.
