Philadelphia Eagles owner Jeffrey Lurie vowed to conduct a thorough search in his quest to find the team's next head coach.

Since firing Andy Reid last Monday, he's lived up to his promise.

The Eagles have already interviewed Atlanta special teams coordinator Keith Armstrong and defensive coordinator Mike Nolan.

They are scheduled to talk to Denver offensive coordinator Mike McCoy today, have meetings set up with Indianapolis offensive coordinator Bruce Arians and Seattle defensive coordinator Gus Bradley for next week, and are expected to ask for an interview with Cincinnati offensive coordinator Jay Gruden.

In addition, the Eagles reportedly interviewed University of Oregon coach Chip Kelly on Saturday and have expressed interest in Syracuse coach Doug Marrone.

Penn State coach Bill O'Brien took himself out of the running by electing to stay with the Nittany Lions.

All of the former NFL coaches currently working in TV - Jon Gruden, Bill Cowher and Brian Billick - are expected to stay in their jobs. San Francisco offensive coordinator Greg Roman, a native of Ventnor and a Holy Spirit High School graduate, has been mentioned as a contender, but has not yet been contacted by the Eagles.

Here's a look at some of the coaches on the Eagles' current list.

Bruce Arians, Colts offensive coordinator

Positives: He's great at developing quarterbacks. Arians has played a major role in rookie Andrew Luck's progress this season. He was also the Colts' quarterbacks coach when they drafted Peyton Manning in the first round in 1998. He also has recent experience as an NFL coach. He took over Indianapolis earlier this season when Chuck Pagano was undergoing treatment for leukemia and led the team to a 9-3 record.

Negatives: At 60, he's the oldest of the candidates. Lurie would seem to be more apt to go after a younger guy with potential, considering Arians would be almost 75 if he lasted as long as Reid with the Eagles.

Keith Armstrong, Falcons special teams coordinator

Positives: At 47, he's among the youngest of the candidates, yet has plenty of NFL experience. He's in his 19th season as an assistant coach. By coaching special teams, he's also used to working with both offensive and defensive players. In addition, he's a native of Levittown, Pa., and played for Temple.

Negatives: Aside from a three-year stint as the Falcons' secondary coach, he's only coached special teams. He would have to hire very strong and experienced offensive and defensive coordinators.

Gus Bradley, Seahawks defensive coordinator

Positives: If Lurie wants to pick a defensive-oriented head coach, Bradley would be a terrific choice. Seattle's defense has been solid over the last four years and has been outstanding this season. They lead the league in points per game, allowing just 15.3. At 46, he's also considered an up-and-comer in the coaching ranks.

Negatives: Bradley doesn't have a great deal of NFL experience. He's been in the league for just seven seasons.

Jay Gruden, Bengals offensive coordinator

Positives: The brother of former NFL head coach Jon Gruden has cut his teeth in a variety of levels. Prior to joining the Bengals last season, he was a head coach in both the United Football League and Arena Football League. He has helped develop Bengals quarterback Andy Dalton and wide receiver A.J. Green into one of the league's most potent tandems.

Negatives: He doesn't seem to anxious to become a NFL head coach. He turned down a request to talk with St. Louis last season about their opening and has yet to express an interest in any job this year.

Chip Kelly, Oregon head coach

Positives: He's one of the most innovative offensive coaches in the country. His spread-option offense with the Ducks enabled him to post a 46-7 record in four seasons. He also has a bit of NFL experience. New England coach Bill Belichick consulted with Kelly in an effort to speed up and improve the Patriots' offense.

Negatives: Other than the meetings with the Patriots, the 49-year-old has never been an NFL position coach or coordinator. In order for an NFL team to hire him, they would have to pay Oregon $3.5 million.

Doug Marrone, Syracuse head coach

Positives: The 48-year-old knows his way around the NFL. He played for two seasons in the 1980s, coached the offensive line for the New York Jets from 2002-05 and served as New Orleans' offensive coordinator in 2006-08.

Negatives: He went to Syracuse in 2009 with a vow to turn the program into a perennial winner, but has yet to deliver. Syracuse went 8-5 this season, but are just 25-25 overall in four seasons, despite competing in a weak Big East Conference.

Mike McCoy, Broncos offensive coordinator

Positives: The 40-year-old is regarded as the top offensive-minded coaching candidate in the league. In addition to putting up big numbers with Peyton Manning as his quarterback this season, McCoy also developed an attack that enabled the Broncos to win a playoff game last season with Tim Tebow as the starter.

Negatives: Other than his youth, there aren't many downsides, which is why the Eagles are going to have to outbid several teams looking for new head coaches if they want McCoy.

Mike Nolan, Falcons defensive coordinator

Positives: Other than Arians, he's the only one of the candidates who knows what it's like to be an NFL head coach. Nolan headed the 49ers for four sesaons (2005-08). The 53-year-old also has a wealth of defensive knowledge, having been a defensive coordinator in the league for 14 seasons.

Negatives: Not a lot, other than a lack of experience with offense. If Lurie decides to go with a defensive specialist as his head coach, Nolan would be a good choice.
