The man is John Hollinger, and the take is limited to the 1977 Finals and beyond for reasons Hollinger explains here, so don’t look for any Russell/Heinsohn/Jones/Cousy appearances.
The Lakers and Michael Jordan dominate the list. By my count, 28 of the 50 spots go to either Jordan or a member of the Lakers, including 14 of the top 20 all-time games.
Four individual Celtics games—and three individual Celtics—make the list.
Whoever can name all four games without looking gets a cookie. Honor code, folks.
