INDIANAPOLIS — You know all about Knicks-Pacers. Oh, boy, do you know about Knicks-Pacers. If you are a regular reader of this column and this sports section — well, first of all, thank you. Second of all, you know that Pacers-Knicks is sort of like a best-of-55 series (with No. 55 Saturday night at Gainbridge Fieldhouse, where the Knicks and Pacers meet for Game 6 of the Eastern Conference finals).

So you know Knicks-Pacers. You’ve got that down.

But you don’t have the complete story of New York-Indiana.

Because for that, you need to go back in time 21 years before the Knicks and Pacers ever met in a playoff series, you need to rewind from 1993 all the way back to 1972, in order to do that. You know how Rick Carlisle has said, stone-faced, that he expects this Knicks-Pacers series to be a 13-day challenge (Saturday being Day 11)?
