STATE COLLEGE — Other than family, football was everything to Joe Paterno. It was his lifeblood. It kept him pumped.

Life could not be the same without it.

“Right now, I’m not the coach. And I’ve got to get used to that,” Paterno said after the Penn State board of trustees fired him at the height of a child sex abuse scandal.

Before he could, he ran out of time.

Paterno, a sainted figure at Penn State for almost half a century, died Sunday at 85.

His death came just 65 days after his son Scott said his father had been diagnosed with lung cancer. Mount Nittany Medical Center said he died at 9:25 a.m. of “metastatic small cell carcinoma of the lung,” an aggressive cancer that has spread from one part of the body to an unrelated area.

Friends and former colleagues believe there were other factors — the kind that wouldn’t appear on a death certificate.

“You can die of heartbreak. I’m sure Joe had some heartbreak, too,” said 82-year-old Bobby Bowden, the former Florida State coach who retired two years ago after 34 seasons in Tallahassee.

Longtime Nebraska coach Tom Osborne said he suspected “the emotional turmoil of the last few weeks might have played into it.”

And Mickey Shuler, who played tight end for Paterno from 1975 to 1977, held his alma mater accountable.

“I don’t think that the Penn State that he helped us to become and all the principles and values and things that he taught were carried out in the handling of his situation,” he said.

Paterno’s death just under three months following his last victory called to mind another coaching great, Alabama’s Paul “Bear” Bryant, who died less than a month after retiring.

“Quit coaching?” Bryant said late in his career. “I’d croak in a week.”

Paterno alluded to the remark made by his friend and rival, saying in 2003: “There isn’t anything in my life anymore except my family and my football. I think about it all the time.”

The winningest coach in major college football, Paterno roamed the Penn State sidelines for 46 seasons, his thick-rimmed glasses, windbreaker and jet-black sneakers as familiar as the Nittany Lions’ blue and white uniforms.

Paterno had been in the hospital since Jan. 13 for observation after what his family called minor complications from his cancer treatments.

On Sunday, two police officers were stationed to block traffic on the street where Paterno’s modest ranch home stands next to a local park. The officers said the family had asked there be no public gathering outside the house, still decorated with a Christmas wreath, so Paterno’s relatives could grieve privately. And, indeed, the street was quiet on a cold winter day.

Paterno’s sons, Scott and Jay, arrived separately at the house late Sunday morning. Jay Paterno, who was his father’s quarterbacks coach, was crying.

“His loss leaves a void in our lives that will never be filled,” the family said in a statement. “He died as he lived. He fought hard until the end, stayed positive, thought only of others and constantly reminded everyone of how blessed his life had been. His ambitions were far reaching, but he never believed he had to leave this Happy Valley to achieve them. He was a man devoted to his family, his university, his players and his community.”

Paterno built a program based on the credo of “Success with Honor,” and he found both. He won 409 games and took the Nittany Lions to 37 bowl games and two national championships. More than 250 of the players he coached went on to the NFL.

Paterno believed success was not measured entirely on the field. From his early days, he had implemented what he called a “grand experiment” — to graduate more players while maintaining success on the field.

The team consistently ranked among the best in the Big Ten for graduating players. As of 2011, it had 49 academic All-Americans, the third-highest among schools in the Football Bowl Subdivision. All but two played under Paterno.

Paterno didn’t intend to become a coach. He played quarterback and defensive back for Brown University and set a school record with 14 career interceptions, but when he graduated in 1950 he planned to go to law school. He said his father hoped he would someday be president.

But when Paterno was 23, a former coach at Brown was moving to Penn State to become the head coach and persuaded Paterno to come with him as an assistant.

He and his wife, Sue, raised five children in State College. He walked to home games and was greeted and wished good luck by fans on the street.
