It didn’t happen every week, but there was no doubt the Arkansas Razorbacks had a dynamic offense this season. And the numbers bear it out.

Arkansas finished the regular season ranked No. 2 in the SEC in total offense (5,482 yards) and points (422) under the guidance of QB Brandon Allen. It was an offense that could, and routinely would, beat you with a balanced ground and air attack.

The senior quarterback threw for 3,125 yards and 29 touchdowns during the regular season, leading the Razorbacks to a 7-5 record, 5-3 in the SEC. Allen certainly has etched his place in Fayetteville lore, and he needs 274 yards in the team’s bowl game to surpass Clint Stoerner for third all-time among the Hogs’ leading passers. Ryan Mallett at No. 2 is in range with a 345-yard game.  Tyler Wilson (7,765 yards) is tops in program history.

Allen has played himself into the NFL draft conversation as he heads out of town. And with him gone, Bret Bielema’s offense will have a different look next season.

Here’s what might change next year.

Quarterback

Brandon Allen is gone, but Arkansas’ starter next season could have an eerily-similar feel and look because Austin Allen will likely enter the spring atop the Razorbacks depth chart. That’s Austin Allen, as in Brandon’s little (6-foot, 1-inch, 210-pound) brother.

Bielema has three other freshmen quarterbacks on his 115-man roster in Rafe Peavey (redshirt) and four-star recruits Ty Storey and Ricky Town. The Razorbacks will also welcome Cole Kelley, a three-star recruit from Lafayette, La., to campus next year.

Allen will be the most experienced of the quarterbacks on next year’s depth chart, having thrown three passes this season — one of them a 35-yard touchdown strike to tight end Jeremy Sprinkle. The sophomore won two Arkansas state high school titles, was named MVP in both championship games, and was Gatorade’s state player of the year. He’ll be pushed hard by Southern California-transfer Ricky Town. The four-star recruit and pro-style pocket passer is already drawing comparisons to Mallett.

There’s sure to be some growing pains, regardless of who is under center. Brandon Allen went through his share of them. But with offensive coordinator and quarterback specialist Dan Enos developing the young group — coupled with talented players returning at the skill positions — the potential is there for the Razorbacks to remain an aerial threat for years to come.

Running Back

The running game has been the Razorbacks’ strength for several years now and 2015 was no different. Alex Collins blistered his way to 1,392 yards and 17 touchdowns — both good enough for third overall among SEC tailbacks. With 52 yards in Arkansas’ bowl game, Collins will move into second on the Hogs’ all-time rushing list and would be less  than 1,000 yards shy of eclipsing Darren McFadden for most rushing yards in a Razorback uniform.

Collins could turn pro.  The nation’s No. 13-ranked rushing leader is sure to drum up interest from NFL teams this spring.  Jonathan Williams, the Hogs’ leading rusher in 2014 with 1,190 yards and 12 touchdowns, already has said he won’t be back. If Collins packs his bags, Bielema is looking at a thinned-out running corps — especially with the uncertainty surrounding third-stringer Rawleigh Williams III, who suffered a scary neck injury midway through the season. Williams is expected to make a recovery, in which he’d join Kody Walker (338 yards, 5 TDs), the squad’s second-leading rusher this year. Three-star recruit T.J. Hammonds of Joe T. Robinson (Little Rock) High School could also be introduced into the backfield rotation next year.

Wide Receiver/Tight End

All the Arkansas pass catchers are all coming back. The talented group is led by top receiver Drew Morgan (751 yards, 10 TDs) and 2014 leading receiver Keon Hatcher (558 yards, 6 TDs), who broke a foot this year in Week 2. The duo will team with fellow rising-senior Dominique Reed (520 yards, 6 TDs) to form a veteran group bolstered by rising-junior Jared Cornelius (358 yards, 3 TDs).

It doesn’t end there. Bielema has an affinity for tight ends, and the coach has two of the best in the SEC in juniors Hunter Henry and Jeremy Sprinkle. Henry (647 yards, 3 TDs) is likely gone as a top NLF pick but  Sprinkle, who has pulled in 308 yards and two more touchdowns (5) than Henry, will be back.

All told, Bielema should return more than 2,100 yards’ worth of offense to Fayetteville for the 2016 campaign. Whoever is Arkansas’ signal caller next year, they won’t have a shortage of talent in which to throw to.
