But Paterno isn't acting his age these days, and that may be the main reason Penn State football is enjoying a resurgence in his 37th year as the team's head coach.
Following consecutive losing seasons, the Nittany Lions are 6-3 and ranked 19th going into Saturday's game against Virginia (6-3) at Beaver Stadium. Before 2000, they had finished with a losing record just once in 62 years.
"All of us were embarrassed with the things that happened here for a couple years," Paterno said. "But Penn State is still Penn State."
And Paterno is still Paterno.
The owner of 333 victories - most of any major college coach - doesn't take defeat lying down. He has been as enthusiastic, animated and emotional as ever - maybe more so.
He has railed against officials, saying poor calls cost his team in overtime losses to Iowa and Michigan. After the Iowa game, Paterno raced over to head referee Dick Honig, grabbed him by the back of the shirt and berated him. Following the Michigan loss, he had athletic director Tim Curley write a letter to Big Ten commissioner Jim Delaney, calling for a review of conference officiating.
Those incidents prove that Paterno remains passionate about his job, but he rejects the notion that he has become more desperate or dyspeptic in his old age.
"You probably won't believe me, but I don't have the slightest idea what people are saying about me," Paterno said. "TV is TV. They're in the entertainment business and they're looking for controversy.
"When I was a younger coach, I was probably much more active in going after officials than I am now. … I don't swear at them. I try to explain to them how they could do a better job."
In fact, Paterno says, he is enjoying this season immensely.
"This has been a fun football team to coach," he said. "I think this is a great bunch of kids. They even laugh at my jokes."
They also play good football. The Nittany Lions have a powerful offense led by senior tailback Larry Johnson, who has rushed for 1,221 yards and 11 touchdowns, and a punishing defense that has allowed just one touchdown in the past three games.
"I think they look like most coaches would want their team to look," said UVa coach Al Groh, who estimates Penn State has eight to 10 seniors who will be picked in the NFL draft.
Despite three frustrating losses - all by a touchdown or less - Paterno and his players take some pride in reversing the program's downward spiral. The Nittany Lions were 9-0 and ranked No. 2 in 1999 when the wheels came off. They lost 14 of their next 17 games, including an 0-4 start in 2001, and critics began saying Paterno was too old to get the job done.
"He's like a god in Pennsylvania," said Virginia linebacker Rich Bedesem, who grew up in Holland, Pa., and went to Paterno's football camp. All of a sudden, however, the septuagenarian coach was looking all too human.
But Penn State rebounded, winning five of its final seven games last season, then made a major statement with a 40-7 shellacking of then-No. 7 Nebraska on Sept. 14.
The Nittany Lions are now bowl-eligible for the first time in three years. Though their Big Ten title hopes are dashed, they want to win out and produce the 19th 10-win season in Paterno's career at Penn State.
"It was sad to hear people say stuff about coach. They didn't know what was going on," said senior receiver Bryant Johnson. "It definitely feels good to hush up the naysayers, people who were saying he couldn't still do it."
If Paterno was motivated to silence his doubters, he isn't saying. But his players have noticed a fire in the old coach's belly, one that hasn't dissipated this week.
Already, Paterno has complained about the scheduling, saying it was "shenanigans" on Virginia's part that forced the game to be moved from its original Sept. 7 date. He was angry when he found out the Cavaliers had a bye week to rest before Saturday's game.
Some say Paterno also was annoyed when Al Golden left after one year on his staff to become UVa's defensive coordinator. And the coach hasn't forgotten that Virginia denied his team a bowl trip last season with a 20-14 victory in the final game.
"He said he was fired up about this game," said Larry Johnson. "He's been like that all season. He's pretty anxious getting this team back where it needs to be."
