He was sentenced to 30 to 60 years in prison.
"These men are good people who made a awful mistake", Boccabella said. "All three ignored the opportunity to put an end to [Sandusky's] crimes when they had a chance to do so".
The scandal led to the firing of beloved football coach Joe Paterno shortly after Sandusky's arrest, and he died of cancer two months later at the age of 85.
Curley was sentenced to seven to 23 months' incarceration and two years' probation, Grace said. "Why he didn't is beyond me".
Spanier said he regretted that "I did not intervene more forcefully".
"It sickens me to think that I might have played a part in children's suffering", Schultz said. "I'm sorry that I didn't do more, and I apologize to the victims", Schultz said. Those men described McQueary's account to Spanier.
"He was a complete and utter failure as a leader when it mattered the most", Ditka said at Friday's hearing.
"Spanier was the ultimate decision-maker when it came to reporting Sandusky", prosecutors wrote, adding that "nothing short of a sentence that includes a period of jail time" would be appropriate.
The three men initially faced more serious charges, including obstruction of justice and perjury, that an appeals court dismissed in 2016 with a ruling the men had been improperly represented during grand jury testimony.

"Spanier's sentence should make it loud and clear that the protection of the welfare of Pennsylvania's children should never take a back seat to the reputation of one man ever again", Shapiro said in the memorandum.
The fallout from creep coach Jerry Sandusky's molestation conviction continues to taint Penn State University.
Prosecutor Patrick Schulte said Curley at one point had drawn up a plan to report Sandusky to state authorities, but "something changed after talking to coach Paterno". Still ongoing are lawsuits involving the university and Paterno's family, the NCAA, Spanier and Louis Freeh, the former FBI director who oversaw the school's damning internal investigation into the case. As a result of the Sandusky case, the university has paid out almost a quarter-billion dollars in fines, court verdicts, settlements and other costs. Paterno, who was sacked in the aftermath of Sandusky's 2011 indictment and died of lung cancer months later, testified he thought McQueary witnessed something sexual, and he urged McQueary to report the incident to Curley.
Judge John Boccabella called the case against Spanier, 68, "a Shakespearean tragedy" and questioned why none of the defendants called police, report the New York Times, the Washington Post, the Pittsburgh Post-Gazette and Pennlive.com in stories here and here.
Two of the cases against Sandusky heavily involved Curley, Schultz and Spanier.
In sentencing memos, prosecutors accused Curley in particular of "astonishing" and unbelievable memory lapses on the witness stand.
