"Bird steals it" gets my vote, but not just because of the incredible finish. It was a game that featured several unique plays, a see-saw fourth quarter and Parish decking Laimbeer. How can that not win?
The Nets comeback was incredible, but the game itself (especially the first three quarters was AWFUL). Even the comeback was scrappy (a ton of free throws) rather than great to watch. (Don't get me wrong, I LOVED it). On the other hand, the Lakers comeback was compelling from start to finish and even had a thrilling finish.
You almost nailed the top five (assuming it's restricted to games most of us have seen!), but I'd have to put the decider against the Pacers in 1991 up there. That was another game that had everything (and I loved that team).
Good poll/thread!
