"He was the source on college basketball," said Terry Taylor, the AP's sports editor from 1992-2013. "He knew coaches, players, games, dates of games and final scores- all manner of factoids- off the top of his head. And when you looked it up, he was always right."

He was a mentor to journalists in the AP and elsewhere. For decades, he coached young reporters in bureaus around the AP on how to cover a game, making sure the play-by-play, the NCAA Tournament implications and the star performances were all put into context.

O'Connell built deep relationships with colleagues, players, executives, referees and coaches, including fellow Hall of Famers Jim Calhoun, John Thompson and Lou Carnesecca.

"Oc and his wife, Annie, were great friends to my wife, Patty, and me when we moved to Long Island to take the job at Hofstra," said Jay Wright, coach of current NCAA champion Villanova. "Oc is the most knowledgeable, ethical, humble college basketball expert ever. He is dependable as a friend and as writer."

A stick boy for the New York Islanders as a teen, O'Connell went to St. John's and joined the AP's sports department in the mid-70s, soon turning a part-time job into a career covering a sport he loved. After leaving to become sports information director at Fordham- where he met his wife, Anne Gregory, the best female basketball player in school history- Oc returned to the AP in 1978.

By 1979, he was boosting the AP's coverage of the Final Four as Magic Johnson and Larry Bird went head-to-head in Salt Lake City. O'Connell had a long chat about basketball with Bird, who was famously reticent about speaking with the media. It was only when O'Connell pulled out a notepad that the Indiana State star clammed up.

O'Connell covered every Final Four from then on, until this year. He kept his Final Four streak alive in 2015, just months after an operation that required partial amputation of his leg. The NCAA made sure O'Connell had a seat at the end of the media table, so he could stretch out his prosthetic.

O'Connell was just as knowledgeable about teams like Rider and Wagner as he was about powerhouse programs like Duke and Kentucky. If a fan asked him about any team, he could tell them what he thought of their chances. For decades, if there was a college basketball game in the New York area, Oc would probably be courtside- whether he was working or not.

Oc's creativity wasn't solely applied to his writing- he did delight, though, in a preseason preview he once began with: "It will be a declaration of independents. ..."

So much a jokester that he once convinced a colleague in the office that World War III had broken out, Oc could make an entire staff of writers and editors crack up even while on deadline.

"Perhaps most importantly, he was beloved by his AP Sports colleagues," Taylor said. "He told funny stories like no one else, and he always had one. He lit up the room when he walked in for his night shift."

AP Executive Editor Sally Buzbee said: "Oc was a true gentleman: Funny- sometimes bitingly so, but gentle, calm, and totally dedicated to his craft. He was loved by his colleagues and by people far, far beyond the AP."

Oc was especially popular around March Madness time, when his pals- even other college basketball experts- would check in to see if he had a sleeper pick for their pools. For three decades, through Magic-Bird, the birth of the Big East, Coach K's entire Duke career, to the one-and-done era, whomever made it to the Final Four, Oc was there to see how it ended and to add more stories to his bottomless supply.

O'Connell is survived by his wife, Anne; sons James and Andrew; and sisters Winnie and Mary.
