Create a player in Homecourt mode. Save and exit. Go to "Play Now" 
at the main menu. Your player will appear on any team you select, as 
long as your profile with that player is loaded. Select any team and 
choose your player and two other players. The other team can be any 
desired. Then, play the game out to 100 with no GameBreakers, 
focusing on the skill you wish to increase. At the end, win or lose, 
your player will still have an increase in attributes. Do this a few 
times to maximize all stats, then go back into Homecourt mode. Play 
through until your baller levels up a few times then repeat. Once 
Homecourt mode is complete and your baller is at level 20, go back 
into "Play Now" mode and completely maximize all his stats.
