Here's a favorite Havlicek memory:
I don't remember the year, but the Celts were playing the Baltimore Bullets at the Garden, and were leading by 14 with a couple of minutes left. Elvin Hayes went on a tear and Baltimore scored 14 straight points to tie it with only a few seconds left. Havlicek took the inbounds pass, raced down the right side of the court and drove the baseline. Elvin Hayes made a nice play to jump out and block the baseline.
Without even pausing, Havlicek spun and dribbled towards the corner, with his back to the basket. He then jumped, turned, and let it fly all in one motion, as time expired. Nothing but net!
