FAIRHOPE, Ala. – Gus Bradley liked the fit.

The Jaguars' second-year head coach liked Doug Marrone's experience, and his approach – and Bradley said those things made Marrone the right choice for a key position on the team's coaching staff.

Marrone, head coach of the Buffalo Bills the past two seasons, on Tuesday afternoon became the Jaguars' assistant head coach-offense/offensive line. Bradley made the hire official while coaching the South team in the 2015 Reese's Senior Bowl.

"What he brings to the table, I think, is experience," Bradley said Tuesday after he and the Jaguars' coaching staff worked the South practice at Fairhope Municipal Stadium.

While the Jaguars made Marrone's hiring official Tuesday, their offensive coordinator position officially remained vacant.

There were national media reports the Jaguars had hired former Oakland Raiders offensive coordinator Greg Olson as the coordinator, but Bradley said late Tuesday afternoon a hire had not been made. Olson was the Jaguars' quarterbacks coach in 2012 under then-head coach Mike Mularkey.

Olson and Bradley worked together on the Tampa Bay Buccaneers' staff in 2008.

"No major decisions have been made yet," Bradley said. "We're still going through the process with that. Hopefully, it will come together soon."

Marrone, 50, who had a 15-17 record in two seasons with the Bills – including a 9-7 record last season— had a 25-25 record in four seasons as head coach at Syracuse from 2009-2012. His record at Syracuse included two bowl victories.

Marrone was the New Orleans Saints' offensive coordinator from 2006-2008, where he worked for Head Coach Sean Payton. He coached the New York Jets' offensive line under Head Coach Herm Edwards from 2002-2005.

"He's had a great background with the offensive line," Bradley said of Marrone. "He's a developmental coach, and he's proven that over the years that he coached the offensive line and things that he did with New Orleans.  Just the impact that he's had even in Buffalo and Syracuse … I think that's what we needed with our offensive line."

Marrone will take over a young offensive line that was coached last year by Luke Butkus, who took over the role after working as an assistant offensive line coach in 2013 under offensive line coach George Yarno. Yarno missed this past season while battling cancer.

"George and I have had many conversations," Bradley said of Yarno's status with the team. "We've had really good open conversations. I think we'll leave that between us to go through."

Marrone coached Buffalo to its first winning season since 2004 this past season, but left the team on December 31. He left during a three-day window following the regular season that allowed him to leave and be paid the $4 million for the final year of his contract.

"I really didn't get into it," Bradley said of Marrone's from the Bills. "For me, it was obviously that he was a good teacher and a good developer and a good person. One thing we feel is really important us humility. If you have humility, you can identify your weaknesses and you can get better at those.

"I just felt a great sense of humility. It was an unbelievable visit."

The Jaguars played the Bills in December 2013, Bradley's first season with the Jaguars and Marrone's first season as head coach of the Bills. The Bills won the game played at EverBank Field in Jacksonville, 27-20. Bradley said he considered the Bills "very well-coached with their offensive line."

"They did a really good job rushing the ball," Bradley said. "That's one thing we've talked about – that running the ball and defense really travels. You build your team and when you get to that point you want to make sure you're good in those areas."

Marrone, who spent the 2001 season as the tight end/offensive tackles coach with Tennessee, was among seven coaches who have interviewed with the Jaguars in the last three weeks. Marrone, contrary to many reports, interviewed specifically for the line position and not the coordinator position that became vacant when Bradley dismissed Jedd Fisch on December 30 after two seasons in the position.

Marrone had a second interview with the Jaguars, which Bradley said elevated the process.

"We wanted to show the interest level we had," Bradley said. "I think not only it was to make sure he was a fit for us, but that we were a fit for him."

The Jaguars interviewed Olson last week, and interviewed New York Jets running backs coach Anthony Lynn and former Denver Broncos offensive coordinator Adam Gase this past weekend. They previously had interviewed Minnesota Vikings running backs coach Kirby Wilson, former San Francisco 49ers offensive coordinator Greg Roman and former Bills offensive coordinator Nathaniel Hackett.

"It's been great," Bradley said. "One of the things we talked about was to be really thorough and get a feel for what they could bring to the table. It's been awesome. Some of these interviews have gone really lengthy. It's been great conversations from scheme to philosophy.

"I think our players are putting great trust in me and our coaching staff to bring the right people in

Bradley also said no candidate has been offered the coordinator position.
