I don’t think a first round series should be in the discussion for the best series of all time. Sure the Bulls Celtics series was memorable and will stay memorable for many years to come…but in the end there was no championship at stake.
When I think of epic battles, I think of championship battles: rockets v knicks (hakeem the dream), bulls v jazz (MJ), spurs v pistons (04-05). If the Bulls Celtics series was your best series of all time, then I’m sorry to say this but you haven’t watched enough basketball.
Aside from championship battles, the battles in the playoffs between the bulls v knicks or the knicks v pacers in the 90s were way more intense.
