Philbin met with team owner Stephen Ross and general manager Jeff Ireland in New York City, where Ross has an office.
"He's a special, special human being," Packers coach Mike McCarthy said Wednesday. "What Joe has gone through, and what his family has gone through, obviously tough is not the proper word. ... His ability to come back meant a lot to all of us. It was not expected, it was not asked of him. But Joe's a class act."
Philbin completed his first interview in South Florida on Jan. 7.
"I think he would make an excellent head coach," McCarthy said. "I've said that before."
Philbin has been with Green Bay since 2003 and has been offensive coordinator since 2007, although McCarthy calls plays. The Packers have ranked in the top 10 in the NFL in yardage each of the past five seasons, including third in 2011.
McCoy completed his first interview with Miami on Monday. He won praise for adapting the offense at midseason when Tim Tebow became the starting quarterback, and the Broncos made an improbable run to the second round of the playoffs before losing Saturday at New England.
The Oakland Raiders also have received permission from Denver to interview McCoy, and they interviewed Bowles.
