Small market, big heart.

Clearly, somebody forgot to get the word out on the small-market conspiracy because, well, look at the NBA’s final four.

Tiny Memphis.

Tiny San Antonio.

Miami, a big market but a fickle one.

And now, the Indiana Pacers, owners of the league’s 22nd-ranked payroll, playing all season without Danny Granger, heading to their first Eastern Conference finals berth in nine years after a series-clinching 106-99 victory over the New York Knicks.

From a first-round loss to the Chicago Bulls two years ago to a second-round loss to the Miami Heat last year ... and now, the next step, the Eastern Conference finals against the Heat.

And given the way they’re playing, given the questions about Dwyane Wade’s knee, well, who knows? They have a puncher’s chance against the mighty Heat. And know this: They will throw their share of punches.

They are not afraid of the Heat. They will not genuflect in front of the Heat. They’ve owned the Heat in Banker’s Life Fieldhouse, and they know they are built better than anyone else in the East to compete with the Heat.

Small market, big heart.

One series away from the NBA Finals.

“Right now we’re turned up, tell you that,’’ Pacers center Roy Hibbert said with a broad smile. “I don’t know if y’all know what that means, but we’re turned up. Hashtag turned up.’’

Turned up.

And heading forward, down to Miami, for a chance to do something improbable but not impossible.

How’d they dispatch the Knicks?

By being themselves, by returning to their basic smash-mouth personality, the type of approach Frank Vogel spoke about the day he was introduced as an interim coach.

All series long, they clubbed the Knicks — and we don’t mean clubbing in the J.R. Smith sense of the word.

All series long, the Pacers owned the boards, both offensively and defensively.

All series long, they owned the paint, Hibbert turning the front of the basket into a no-fly zone.

All series long, they defended like rabid dogs, running the 3-ball-happy Knicks off the 3-point line in every game except Game 6. Paul George did a remarkable job, keeping Carmelo Anthony under his season average in four of six games.
