I miss Red.
With Bias, I have very mixed feelings. The guy had the potential to be a superstar. It wasn't fate or bad luck that took that away, but instead his own actions. I'm in no way saying he deserved what happened, but I never formed the same attachment I did to Bias that I did to Red, D.J., or Reggie, all of whom were Celtics greats who passed away recently.
It's the ultimate "might have been", though. If Bias hadn't died, maybe that takes some strain off Bird and McHale, maybe lengthening their prime. If we had been lucky enough to still draft Reggie, and he hadn't had his own tragedy, I think the landscape in the late 80s / early 90s could have looked quite different.
