How have you got so far so quick? Simulating the games or do just play short games?
I play GM and simulate the whole regular season. I do the development and scouting every week of course. Also making sure to alter the rotation to keep players happy, and trading players away if the minute distribution isn't working.
If I make the playoffs then I play the entire playoffs using best of 5, then best of 7 for the finals.
If I miss the playoffs then obviously I wasn't that great of a GM and I try to make the playoffs the next season by either drafting well or making some trades. The scouting system in NBA 2k8 is niiiiiiice.
PG- Deron Williams - 98
SG- Sean Mann (draft pic) - 91
SF- Josh Smith - 93
PF- Tyson Teague (draft pic) - 86 (rookie)
C- Andrew Bynum - 90
PG- Acie Law - 81
SG- Josh Childress - 84 (sixth man)
SF- Luke Walton - 78
PF- Sheldon Williams - 78
C - Herb Wheeler (draft pic) - 77
PF - Hakim Warrick - 79
PF- Soloman Jones - 72
All players are 75+ morale as well. Didnt make the playoffs the first two years, but made some nic draft pics and trades, then won the 'ship last year, and just entered the playoffs as the #1 seed this season.
