The 7 New NBA Finals Game 7 Rules (page 2)
7) Less is More
If a team is down during crunch time or their egos are up during all the time, the coach has the option to play half the players for double the points. With only three players on the court, no subs allowed until a timeout, regular two–and three-pointers are now worth four and six points. The other coach can determine that they want to even the playing field, point-wise, and take out all but three of their players to also shoot for four and six point shots, or maintain seven players with subs for two and three points as per usual.
Pros: Teams with confident, strong trios can advance their scoring in half the time, making fourth quarter comebacks and halftime leads even more dramatic.
Cons: All basketball teams now only have three players so the college draft is screwed.
