FAYETTEVILLE - The two newest members of the Arkansas coaching staff were introduced Monday at the Fred W. Smith Football Center.

FAYETTEVILLE - The two newest members of the Arkansas coaching staff were introduced Monday at the Fred W. Smith Football Center.

Defensive backs coach Paul Rhoads and running backs coach Reggie Mitchell met with the media after coach Bret Bielema. Rhoads was hired Wednesday, replacing Clay Jennings and Mitchell was hired February 12, replacing Jemal Singleton. Jennings left Arkansas for Texas and Singleton went to the NFL with the Indianapolis Colts.

Mitchell said he fell into the gig at Arkansas. He goes back with Dan Enos, the Arkansas offensive coordinator. Both worked at Michigan State, albeit at different times. Enos actually replaced Mitchell in East Lansing. Mitchell wanted to help his colleague by making a recommendation and was surprised at Enos’ response.

"When I left Michigan State he replaced me at Michigan State. And then we have just kind of known each other on the recruiting trail and he coached at Central Michigan and was the head coach there and I played at Central so I would send him a text when they did something well."

Rhoads’ had history with current Arkansas athletics people, too. He is familiar with athletic director Jeff Long from their mutual time at Pittsburgh. And Rhoads shares an agent with Arkansas defensive coordinator Robb Smith. When the job came open, Rhoads contacted Smith about the possibility.

"Quite honestly I’m looking forward to having my own room back, my own position room and that be my concern," Rhoads said. After 16 years of either calling plays and either putting a defense together or making the decisions that affect the entire program, getting back to the grass roots and having the opportunity to teach and coach on a daily basis in one room, I’m extremely excited about."

Movement on the Line

Although spring practice has not yet begun, Bielema did hint at further shifts when it does start in earnest in a couple weeks.

Bielema had already said former defensive tackle Hjalte Froholdt would make the switch to the offensive line, but he made it clear Monday that Froholdt was working specifically at center. He was joined by Frank Ragnow, a returning starter from last year, though at guard. The only other natural center on the roster is Zach Rogers, a sophomore who played only a handful of snaps in 2015.

"I think Hjalte Froholdt, to say that he’s been a natural transition would be an understatement," Bielema said. "I think he really has caught on to the inside position very, very well. I like where he’s at and the amount of progress he’s made."

Josh Allen, who played guard last year during practices, has moved to the defensive line. Allen is also currently suspended for one week.

Other returns

Tight end C.J. O’Grady, linebackers Dre Greenlaw and Jamario Bell are back on the team after being suspended by Bielema earlier this month because of academic issues.

O’Grady and Greenlaw played last year; Greenlaw was even on the SEC All-Freshman team. Neither are long-term questions. Bell may be, Bielema said.

"Jamario Bell could down as one of the greatest achievements or greatest underachievements in my coaching career," Bielema said. "He’s very talented, he’s got a very, very blessed appearance. He’s got all the physical demeanor and everything. But my man just has to take the academic world a lot more serious."

Starter, But Not

Austin Allen is the current pegged starter for the 2016 season. That doesn’t mean much in February, though.

Bielema had tabbed Allen as the leader at the position the last time he met with the media on National Signing Day. Allen was the clear No. 1, Bielema said. His other quarterbacks aren’t buying that.

"I asked (Enos) how the QB meetings were and he said very anti-social," Bielema said. "I think when BA was in the room, everybody kind of knew what was going on. I think now all those guys are smelling blood and everybody’s working and competing, and I think that’s a good thing."

The depth chart in early February went Allen, sophomore Rafe Peavey, redshirt freshman Ty Storey and redshirt freshman Ricky Town. It was unclear whether that had changed, but Bielema was happy about the progress each had made in the last month.

"(Peavey) looks great," Bielema said. "I know he’s around, he’s doing things. … Ty Storey looks to have continued to develop his body. He looks really, really good. … Ricky I think has made huge progress. He’s a very intelligent kid."

It’s unlikely Bielema names an actual starter until the fall.
