Again, your bias is showing.
What years were the 76ers more stacked than the Lakers or Celts during the 80s? NEVER.
The Fo, Fi, Fo 6ers were the best of the lot, and had a past-prime Doc and Moses Malone. There are a lot of familiar names like your Doug Collins and Darryl Dawkins and Mo Cheeks, but they were just really good pieces. Lakers and Celts boasted 3+ HOFers basically every year of the 80's. Most in their primes. Magic, Worthy, Kareem. Bird, McHale, Chief. Their benches had better pieces throughout the decade than those early-mid 80s 76er teams. The Celts had HoFers on the bench like Tiny Archibald and Dennis Johnson and the Lakers had the best bench/role players for the majority of the decade. AC Green, Byron Scott, Michael Cooper, Bob McAdo (HOF), Norm Nixon, Kurt Rambis, Mychal Thompson...it's ing hard to find a team that surrounded their stars with better castmates than the Lakers did in the 80s.
You're wrong, Chang.
