Before I entered a dynasty mode, I placed all the top nba players in one team. Trade away all the low-rated players of your favorite team & get all the best players like kg, kobe, shaq, tmac, duncan, kidd, pierce, webber, carter, ai, francis, etc, etc.
Then, enter the dynasty mode (82 games). Simulate all the games, up until the finals. Upon winning the championships (by this time you should be having a message about upadating your ea sports bio. just 'save' it), go ahead through all those rookie draft, re-signing of players, free agent signing, etc at the end of the season. You can also simulate the training camp.
After this, at the start of the 2nd season, save your dynasty game and exit the dynasty mode.
Check your "my nba live" and... viola! You now have at least 5,000+ added points for you to spend in the nba store. All that in just about 5 minutes, without playing a single game.
