The pool of candidates appears to have dwindled. Chicago Bears special teams coordinator Dave Toub is out of the running and has re-signed with the Bears to remain in his present position. Bengals defensive coordinator Mike Zimmer, who is candidate for the Tampa Bay job, has also been eliminated from consideration.
Philbin, Bowles and McCoy have interviewed with various teams recently, meaning the Dolphins have competition.
Philbin and McCoy have both talked with the Tampa Bay Buccaneers, and Oakland has expressed interest in McCoy. Bowles has met with the Raiders. The Indianapolis Colts, which fired Jim Caldwell on Tuesday, could also become a factor in the selection process.
The Dolphins hope to select a head coach in time for next week's Senior Bowl, which doubles as a job fair for NFL assistants.
The Packers offense has been impressive during Philbin's tenure as offensive coordinator, but he doesn't call the plays for Green Bay. Head coach Mike McCarthy does. However, Philbin, 50, has been credited with Aaron Rodgers' steady progression, and he might have another promising quarterback ready to blossom in backup Matt Flynn, who expects to be an unrestricted free agent.
Philbin's unit finished third in total yards and first in points per game in 2011.
McCoy, who is 39, has spent two seasons as a passing game coordinator in Carolina, and spent two years as the offensive coordinator in Denver. He helped revamp the Broncos' offensive once Tim Tebow became Denver's starter this season. But his unit finished 23rd in total yards per game, and 25th in points per game in 2011. Both rankings are behind this year's Dolphins offense, which finished 22nd in total yards per game and 20th in points per game.
This is the fourth time Bowles, 49, has been a candidate for a head coach position. He led the Dolphins to a 3-1 record as Miami's interim coach, but has never served as a coordinator in his 12 seasons as an NFL assistant.
