You often hear announcers talk about the first team to a hundred usually wins. If the rule was actually that the first team to reach a 100 points is the winner of the game, how do you think that would affect the strategy if at all?
Only thing that should change is the length of games
This. Some teams like the Pacers, Bulls, Grizzlies, and Nets would routinely have 50+ minute games; and teams like the Thunder, Spurs, Clippers, and Rockets would get a lot of games done in about 40 minutes.
