Just looked at the classic rosters - which you can play with right from the start. At first I though you might have to unlock the teams by beating the Jordan Challenge, but that's not the case.
The got all the main guys for the Bulls teams. Pretty much only missing the 10th, 11th or 12th man. The biggest Bulls name not on the roster that's missing, in my opinion, is Scott Williams (who was on the first 3 title teams) out side of that, the Bulls rosters are very good.
The other classic teams, they got all the starting lineups. And some of the teams have 1, maybe 2 bench players. Some have none. The 1986 Celtics have the starting lineup, but no bench players like Bill Walton or Sam Vincent.
They basically have a few bench players from other teams, and ones who have played for the Bulls - Steve Kerr is on the 90 Cavs, Cliff Levingston is on the 1990 Hawks etc.
Here's the 8 Bulls teams and the players that are missing. You can't edit existing players - which is kind of a pain. You can create a new player and place them on the team. But I don't think I'm gonna go through the trouble. The problem is all the filler players have the same names - Richard Johnson, William Jones etc..
1986 Bulls
They got all the starters here and a few bench guys. They have George Gervin on the Bulls. I guess the biggest missing name is Gene Banks. But I'm not to broken up over that.
1990 Bulls
Got the first 10 guys. Only missing Jeff Sanders and Charles Davis. Again, not heartbreaking.
1991 Bulls
Just missing Scott Williams and Dennis Hopson.
1992 Bulls
Got the first 10 players. Missing Scott Williams and Bobby Hansen
1995 Bulls
Got the first 10 guys. Missing Larry Krystkowiak, Corie Blount, Dickey Simpkins, Pete Myers. Some combination for the 11th and 12th man. But no biggie.
1996 Bulls
They got the first 10 guys. Biggest names missing from this team are Randy Brown and Jason Caffey. They could have used James Edwards here. Edwards is on the 1990 Pistons rosters and they could have plugged him in on this Bulls team. But oh well. No John Salley or Jack Haley either. Jack Haley and his 1 game played in 1995-96 lol.
1997 Bulls
Got the first 10 guys. Missing Brian Williams, Jason Caffey and Randy Brown
1998 Bulls
Got the first 10. No Scott Burrell or Randy Brown.
Overall, 2K did a great job getting the players they did. I just wish they gave you the option of editing the filler players. I don't know if I want to go through the trouble of creating all the other guys. Maybe Scott Williams and Randy Brown.
