The hall of fame in Dynasty mode should also have the retired jerseys of players from non- user controlled teams. This will really give players a greater sense of achievment when playing the dynsty mode.
EA could do this by keeping track of all player achievments (all star selection,MVP, first/second team selections,etc.).
The game should also keep track of all player achievments prior to the 2005 season.
For example, Shaq has been selected in the NBA 1st/2nd team, Allstar team a couple of times, Finals MVP 3 times. When Shaq retires in, let say 2009, the game will read all credentials prior to the 2005 season plus credentials after the 2005 season. This in part will make Shaq a hall of famer, even though the Lakers (???) are not a user controlled team.
Also in the Hall of fame, all stats could achievments are posted and could be viewed.
