Thousands of mourners, including Steelers players and former President Barack Obama, gathered Tuesday at the funeral of Steelers Chairman Dan Rooney.

Cardinal Donald Wuerl, the archbishop of Washington and former bishop of the Pittsburgh diocese, recalled Rooney’s “huge and caring heart” while offering the homily during 80-minute funeral Mass at St. Paul’s Cathedral in Oakland.

“You can get anything done if it doesn’t matter who gets the credit, and he never sought the credit,” Wuerl said.

Dignitaries from Obama to former Secretary of Homeland Security Tom Ridge attended the service, as did countless former and current Steelers players and staff members.

“Dan Rooney is a giant. In two days, we lost two giants in this city: Dan Rooney and Henry Hillman. The problem is they don’t make them like that anymore,” said U.S. Rep. Mike Doyle. “A lot of the things Dan Rooney did people didn’t know about. He did a lot of these things anonymously because that’s the way he was.

“He was deeply religious man, a family man…”

Hall of Famers Joe Greene, Franco Harris and Mel Blount were among those in attendance, as was Pirates owner Bob Nutting.

NFL Commissioner Roger Goodell and Dallas Cowboys owner Jerry Jones also were at the church.
