Oh, we of little memory.

Villanova hit a three-point shot as time expired to defeat North Carolina 77-74 in the championship game of the NCAA Tournament, and some are calling it the greatest final played.

Hang on a minute.

This one wasn’t even the greatest final involving Villanova.

The greatest NCAA title-game victory, in my opinion, was Villanova’s 66-64 shock victory over national No. 1 Georgetown and Patrick Ewing to conclude the 1984-85 season.

Rollie Massimino’s team played what Sports Illustrated called “the perfect game” — and they needed it to win the title after being seeded No. 8 in their region.

Villanova is still the lowest seed to win the championship, and I don’t see any other 8s winning this any time soon.

This was a thoroughly unlikely game, played before a national audience fully expecting a victory by the defending champion Hoyas, who had rolled over the five previous tournament opponents, including conference rival St. John’s 77-59 in the Final Four.

Villanova had only one way to win it — slow the pace, work the ball — hold it, if necessary — take only high-percentage shots and play defense.

Anything else, and Georgetown wins by 15.

Villanova pulled this off by shooting 22-of-28 from the floor, a mind-boggling 78.6 percent, an NCAA title-game record, by a comfortable, then as now.

Villanova walked a high wire throughout the tournament, keeping scores low, taking high-percentage shots — often at the end of a long time holding the ball. (The shot clock did not come in until the following season, and the three-point shot the season after that.)

Check their scores:

51-49 over No. 9 seed Dayton; 59-55 over regional top seed Michigan; 46-43 over regional No. 5 seed Maryland; 56-44 over regional No. 2 seed North Carolina; 52-45 over Midwest Regional winners (and No 2 seed) Memphis State.

And then the shock over Georgetown.

No, this one did not have hectic charging up and down, or a three-pointer. (For obvious reasons.)

But it had a particularly intelligent approach to the game by Villanova, and the longer the Wildcats stayed in the game the more ridiculous it seemed. They can’t actually win, can they?

All 66 of their points were scored by their starters. Three subs played a total of nine minutes and did not take a shot. Three starters played all 40 minutes.

Ed Pinckney and a zone defense was key in keeping Ewing, soon to be the NBA’s top draft pick, under control.

Also important was Villanova never shooting before a good shot presented itself. Even if that took 60-plus seconds of passing around the ball.

It was in doubt nearly to the end. Georgetown led 54-53 on a shot by David Wingate. He turned over the ball on the next trip, when the Hoyas could have taken a three-point lead, and Harold Jensen hit an uncontested 15-footer, and Villanova was never headed.

Then final two minutes featured the Hoyas mostly missing shots and then fouling Villanova players to get back the ball. Despite missing the front end of three 1-and-1s, the Wildcats managed to sink enough free throws to keep Georgetown at bay. The game ended withn Dwayne McClain grabbing an inbounds pass with two seconds to play, and falling to the ground clutching it — till the buzzer sounded.

I was working at The Sun in San Bernardino, watching this game on TV, preparing to lead the Monday night newspaper with it, and we were astonished that Villanova — unranked before the tournament, a loser of 10 games, including two to the Hoyas — won. Georgetown was that kind of force back then.

That remains the best NCAA title game, to me, because it was so unexpected, it was won in a fashion we will never see repeated, and it was, as Sports Illustrated put it … a perfect game.
