The last three days have been filled with flashbacks for the Knicks — glimpses of the past, injections of nostalgia, reminders of what once was in the franchise’s history — and snippets of what the future could look like.

First, there was the halftime ceremony Saturday to honor the 50th anniversary of the 1972-73 title team. Tuesday will mark the 20th anniversary of Patrick Ewing’s jersey retirement ceremony, with his No. 33 the most recent jersey to go up to the rafters. And this week, the Knicks enter a pivotal stretch against Atlantic Division opponents, which started with a 109-94 win over the Celtics Monday night that allowed them to take control of a top-five position in the Eastern Conference.

It’s an interesting juncture in the Knicks’ modern history, as celebrations about the past and optimism about the short-term future have become intertwined. But there’s something missing from this run, or rather the groups from the last decade or so that preceded it.

The celebrations are lacking a tinge of recency. They’re missing a reason to start new anniversaries. And while jersey retirements have sparked separate debates for Charles Oakley and Bernard King, with Carmelo Anthony even giving his own pitch, it’s unclear where this next generation of title celebrations and jersey retirements could lead. It’ll be facing them Tuesday once Ewing’s anniversary arrives. The tweets. The videos. Maybe even a replay of the ceremony on YouTube.
