open up a quick game and set the home team as either LAS ANGELES LAKERS or LAS ANGELES CLIPPERS and the other as the away. then hit "y" and set the difficulty to "hall of fame" and quarter length to "1" minute. Now start the game. when the tipoff is over pause the game and go to "Options", then "my NBA" and then "game sliders". on the first page you will see 3point success , jack it up to 100 and then go back to the game. NOW, just keep launching 3 pointers and the game will be won easily and it will only take about 8 minutes a game. so an easy 180 gamerpts for all the rivalry games.
