FAYETTEVILLE - Two things are true about depth charts, especially ones at the beginning of the season. 

One: just because a player is listed as the No. 2 somewhere doesn't mean he will actually be the second player in at that position.

Two: Just because a player is not listed anywhere doesn't mean he won't play.

Beyond that, sure, depth charts are a valuable tool; the "OR" and "AND" caveats aside. 

Arkansas released its first of the calendar year 2016 Monday ahead of this week's season-opener against Louisiana Tech. The last time the Razorbacks had a depth chart, Brandon Allen was still the starting quarterback. Coach Bret Bielema declined to offer one during the spring as most coaches and teams do, then didn't do one to start the fall, either.

Still, little was surprising Monday. 

Bijhon Jackson wasn't listed at defensive tackle. McTelvin Agim was. Kody Walker was called the starter at running back, but he may not play at all dealing with a foot injury. The chart used a base 4-3, a formation Arkansas might use 15 percent of snaps this year defensively. It also included an I-formation on offense, another rarity.

One of the most curious things to watch Saturday will be Walker's spot at running back. The sixth-year senior is exactly that because he has been injured every season he's been in Fayetteville. Listed alongside him as a starter - one of those ever-there "OR" situations - was Rawleigh Williams III. Williams lost half of his year last season after breaking his neck against Auburn. Freshman Devwah Whaley and Duwop Mitchell were side-by-side "OR" as the back-ups.

"Rawleigh is just champing at the bit. It’s going to be hard to pull (No.) 22 out of the game," Bielema said. "He just really … he looks good, he’s mature, his demeanor."

Arkansas is a three-plus touchdown favorite against Louisiana Tech (Saturday, 3 p.m. at Donald W. Reynolds Stadium. A margin greater than that might see freshman T.J. Hammonds, who still may be ticketed for a redshirt or perhaps a position change, and Juan Day see carries in the waning minutes.

As for the two spots of concern most of camp - offensive line and linebacker - everything panned out the same as it had been the last days of fall.

Dan Skipper-Hjalte Froholdt-Frank Ragnow-Jake Raulerson-Colton Jackson, from left to right, are the starters. Brian Wallace backs up Skipper on the left and Jalen Merrick on the right. Zach Rogers is listed only as the back-up at center, but likely would be the first interior lineman off the bench if the opportunity presented.

Brooks Ellis and Dre Greenlaw are in the middle and weakside, respectively. Those terms rarely matter considering Arkansas will roll a nickel package, a 4-2-5, more often than not. On the few occasions that does happen, Khalia Hackett then Josh Williams will play the strongside. What's more interesting there is who the first replacement for a fatigued Ellis or Greenlaw might be when the team runs that 4-2-5. It could be Hackett or back-up middle linebacker De'Jon Harris.

Wide receiver remains a cluster, but in the best possible ways. Drew Morgan and Keon Hatcher are co-starters on one side while Cody Hollister and Jared Cornelius are co-starters on the other. Dominique Reed "OR" Deon Stewart back up those two, while Jordan Jones then D'Vone McClure are opposite.

There was precisely one question thrown at Bielema in the half hour about quarterback. A shockingly low number considering the starter at the position, Austin Allen, has exactly 19 career pass attempts. No one seems to be worried about how he will step into the limelight.

Few are worried about how Arkansas will do with a little more focus on them in 2016 across the country. It isn't uncommon to see projections from national publications showing Arkansas beating Alabama. If that were to happen, the 9-3 predictions some are so fond of this offseason, are legitimate.

Just don't base it all off that first depth chart. Louisiana Tech need not be another Toledo.

"One of the things that our guys have talked about is starting fast. And last year we did not start fast in our first four games," Bielema said. "As a result of that we were a 1-3 team coming out of it. So that element is out there good enough."
