Expansion really watered things down. IMO, its a big reason why offense suffered so much from the late 80s until the early 00's. Officiating was also a big reason. But you didnt have 5 man lineups like the Celtics, Sixers, and Lakers had in the 80s anymore. That and free agency changes around 1988 or so made it easier for guys to change teams, also diluting strong teams. So, I dont think you get a golden era unless Bias is every bit as good as Jordan. And it would be better if Bias was battling Jordan. Dont mess with Jordan!
