MOBILE, Ala. – Senior Bowl Week rolls on.

Let's get to it … James from Jacksonville:
I have never been a fan of hiring an assistant head coach. In my opinion, there is a general manager, a head coach, an offensive coordinator, a defensive coordinator and the position coaches. I simply don't understand the Doug Marrone hire. I know the logical answer is "the Jaguars believe that hiring Marrone will make them a better team in 2015." I get it, but I worked in a restaurant once and I quit because there were too many cooks in the kitchen. Are you following my train of thought?
John: I am following, but your train is on a different track than that of the Jaguars – and I wouldn't overthink or overstress this one. The Jaguars hired Doug Marrone on Tuesday as assistant head coach-offense/offensive line, but his role is first and foremost to coach the offensive line. The assistant head coach-offense part of his title isn't something at which to scoff, but it's also not going to cause any confusion or create a situation where there are too many cooks or kitchens or whatever – oh, and sorry your job didn't work out.
Paul from Arlington, VA:
So, is Greg Olson the offensive coordinator or not?
John: I got many variations of this question Tuesday afternoon as Twitter blew up following reports that Greg Olson had been named the Jaguars' offensive coordinator. I got the question a lot more Tuesday night when there were more reports. The early reports were not correct. The later reports still weren't quite official, but I expect Olson – the Jaguars' quarterbacks' coach in 2012 and the Oakland Raiders' offensive coordinator the past two seasons – to be the offensive coordinator of the Jaguars very, very soon.
Chris from Niagara Falls, NY:
I'm not sure what the obsession is over our new offensive coordinator. Players play, coaches coach. A good offensive coordinator can only be as productive as the talent he is given. There is no magic wand.
John: It's January. That means NFL fans want to know what's going on with their team. It's 2015. That means Twitter and the internet exist, so things that were once interesting and newsworthy now merit obsessive behavior. That's the sports world we live in, magic wand or not.
Ryan from Long Island, NY:
Assembling the brain trust...Marrone is a true football guy...great hire for the team in any capacity!
John: There is something to be said for hiring experience – and Marrone certainly has that. If there is anything to be gained from a coach with a hard-nosed, rock-solid reputation who has "been there, seen that," Marrone certainly brings that. He has been an NFL head coach and a college head coach. He has been an NFL coordinator and an NFL offensive line coach. He indeed has a reputation as a true football guy. Gus Bradley likes Marrone's experience and he likes that he's a developmental coach. What he'd really like him to do is make the offensive line play better. Stay tuned.
William from Section 432:
With Doug Marrone getting hired with his "special title," Trestman going to the Ravens leaving Adam Gase one option in the Jaguars' offensive coordinator position, and Greg Olson likely to come here ... Your "speculation" was pretty spot on.
John: We all do the best we can. The parts on this have been moving all week and continue to move. Adam Gase reportedly was flying to interview with the Chicago Bears on Tuesday night. And so it goes.
Rob from Fleming Island, FL:
Forget about Blaine at away games … how about MJD running hard behind Greg Jones this season? Surprised we didn't rank higher in rushing yards.
John: It's one of life's mysteries.
Wallace from Jacksonville:
I think it's safe to say that significant improvement from the offensive line is a key to more success next season. What can the offensive linemen do in the offseason to get better? I suspect hitting the weight room hard and eating right to support strength training is part of the plan, but is there anything else they can do "on their own?"
John: The weight room will be a huge part of it, and that will be the focus until the offseason program begins in mid-April. At that point, technique will be a focus, as well as pretty intense film study and review. Or at least it needs to be. A big part of the issue for the line last season was communication and blitz pickup. Improvement in that area should come with experience, but getting into the film room and being more familiar with defensive looks is big, too.
Matt from Gainesville, FL:
Any way Jacksonville could get Darrell Bevell for offensive coordinator? Seems like a good fit, a run heavy offense that isn't afraid to air it out.
John: Why would Bevell leave a Super Bowl team for a lateral move?
James from Jacksonville:
Has Boselli ever had any interest in coaching offensive line in Jacksonville? Has he ever been asked?
John: I'm sure at some point Tony Boselli would be and will be interested in an NFL offensive line coaching position. A big reason he is working with the Jaguars' coaching staff this week coaching the South team is to gain experience – perhaps toward such a position someday. For now, Boselli is committed to coaching his sons, who are still in high school. Pursuing NFL opportunities likely will come after that – if he indeed pursues it.
James from Jacksonville:
Have you heard the saying "Jacksonville is where players and coaches come to die?" What does that mean?
John: I've never heard the saying, and I suppose it means it's impossible to have success playing or coaching for the Jaguars. If I'm right and that's what it means, it's a pretty stupid saying.
Bryan from Jacksonville:
Can staffs from teams not coaching in the Senior Bowl attend for the purpose of scouting players?
John: Yes, and almost all coaching staffs do attend the Senior Bowl. The exceptions are the teams playing in the Super Bowl. Scouting staffs from all 32 teams attend. The advantage staffs who coach the team get is they get to know the players on a more personal level.
Peter from Maribor, Slovenia:
Good fathers make good sons... You're doing great, John. One year, huh?
John: Tuesday indeed marked a year to the day since my father, Richard Edgbert Oehser, died at 83. The outpouring of support from O-Zone readers moved me then, and the memory of that outpouring moves me now. RIP, Dad. Moving on.
Tyler from Jacksonville:
We are on the green, two feet out. Let's knock this one in and send Bortles home ... or close enough, to Tampa, along with our pick at No. 3 to bring the Jaguars the ELITE quarterback they so desperately need: Famous Jameis Winston! P.S. I do think Bortles will be good though, but he isn't Jameis. GO JAGS!!!
John: Yeah … you're going to fritter away a lot of time and energy this offseason – and set yourself up for a lot of disappointment – if you're waiting on this.
William from Smyrna, TN:
John, after reading another O-Zone, it just occurred to me: Do teams like their fans to "get into" the goings-on of the team or just to purchase tickets, attend games, shout and get slobber happy during the action and then go home and return the following week for more insanity?
John: The Jaguars want fans as engaged as possible every day, every week, every month, every year. It's why this feature you're reading exists.
John from Jacksonville:
This may sound like a strange comment but I would much rather be a Jags fan this offseason than a Packers fan. Being five minutes away from almost a sure win to get to the Super Bowl and committing one of the all-time team breakdowns in recent history is much more difficult in an offseason than having an ending like the Jags had. I wouldn't wish that feeling on any team's fan.
John: No doubt the Packers, their fans and anyone associated with the organization is hurting. But while there is no organization I'd rather be associated with than the Jaguars, I can't say I'd rather have a 3-13 season than a conference runner-up season. No matter how much losing in the postseason hurts, you'd rather get there and fall short than not get there.
Eder from Mexico City, NM:
Can you explain us what is the difference between an offensive line coach and one assistant coach/ offensive line coach?
John: On a day-to-day basis, not much. Doug Marrone likely will work with the offensive line first and foremost, but the assistant head coach title gives him a bit more clout in the building. If the head coach is unavailable for some reason, then the assistant head coach often steps in and runs practice and team meetings. He also may have more of a voice in coaches meetings and game-planning meetings. But realistically, his role will clearly and concisely be offensive line coach.
