Don't expect him to exult over the highs: the Ravens' Super Bowl championship, the 31 years as chairman of the NFL's broadcast committee, the launching of Monday Night Football or his role in persuading fellow owners to share television revenue.
Paul Brown, the death of Ernie Davis from leukemia, the Browns' heartbreaking losses to the Denver Broncos in the 1986, 1987 and 1989 AFC championship games, the financial morass that forced him to move the Browns to Baltimore - and eventually forced him to sell the team.
No. On the eve of what could be his final game as the owner of an NFL team, Arthur B. Modell prefers to look forward.
"I don't indulge in nostalgia," he said. "I've had a very good run. I'm grateful for it.
"I have no regrets. I'm proud of my achievements, I'm proud of my contributions to the good and welfare of the league."
Ravens President David Modell said his father's "don't look back" philosophy extends to his private life. Once, on a business trip, David Modell asked to see the house where his father grew up in Brooklyn.
But Art Modell said no.
"And it's not that he just wouldn't do it - he refuses to do it," David Modell said. "He says, 'No, I don't want to do that. I don't look back; I look forward.'"
The Ravens and nearly 70,000 fans at M&T Bank Stadium will salute Modell in a ceremony during halftime of tonight's nationally televised season finale against the division rival Pittsburgh Steelers. If the Ravens win, Modell's ownership tenure will extend into the playoffs.
In a rare interview, Bisciotti, who will exercise his option to buy the remaining 51 percent of the Ravens for $325 million in April, called the apprenticeship "invaluable."
"I've got not only an owner, but I've got one of the most experienced owners in the room," he said. "I've been able to go into these NFL meetings and learn from the group and then have it explained to me in detail by Art."
Bisciotti said he admires Modell for "the promotion of league-think."
"You see the state of the other professional leagues, and his greatest accomplishment is in building this business of the NFL to the prominence that it is," he said. "And it all centered around unselfishness."
Bisciotti said that when Modell bought the Cleveland franchise, it was one of the league's best. "There was a lot to gain by not sharing." But Modell had "the foresight to realize if you could sacrifice your short-term gain, you would have long-term gains that far exceeded it," he said.
The New York Giants' owner, Wellington Mara, said Modell should be credited as an innovator. The two met at an owners meeting after Modell bought the Browns for $4 million in 1961. Modell calls Mara, 87, "one of my dear friends."
"He should be remembered certainly with respect, almost with reverence I would say, because of the contributions he made to the league through the many years," Mara said.
