Some hefty expectations have fallen into the hands of Bret Bielema and his Razorbacks team. Last season, Bielema led Arkansas to its first bowl game in three years. This season, people are talking about winning the SEC West.

The preseason Associated Press Poll has Arkansas ranked No. 18. The Coaches Poll has Arkansas ranked No. 20. It’s clear most of the country is expecting an explosive year from Bielema’s Razorbacks, and from how they’ve looked during preseason camp, the players are ready to deliver.

Here are the five biggest developments from Arkansas’ preseason camp:

1. Defensive line the most surprising squad of fall camp: At least, that’s according to Bielema. Even though offensive linemen were in primarily in the spotlight this offseason, especially since they were featured on Arkansas’ SEC Media Guide, Bielema wanted to make sure his team knew that he respected both lines. That’s why he gave his defensive linemen shirts with “Front Force” on them (the “force” is spelled with a 4). Originally the idea of defensive line coach Rory Segrest, Bielema felt the D-line had earned the right to have them. Indeed, both first and second-team defensive lines drew praise from Bielema during the Razorbacks’ last scrimmage of preseason camp.

2. Running game will stay strong: Who is replacing Jonathan Williams? It’s been a pressing question ever since the reliable running back sustained his season-ending injury. However, what was seen as devastating then could be an opportunity now. Alex Collins will, of course, become the most prominent back. But also in the mix are Kody Walker and Rawleigh Williams III, known formerly as Jonathan Williams’ “shadow.” Both running backs had great camps, and Williams played well during the Razorbacks’ Saturday scrimmage, with six or seven carries for 45 yards and a touchdown from the red zone. Bielema did state that his best running attacks have always involved three rotating backs, so the rushing offense may look different but will remain productive.

3. It’s hard to narrow down the receivers: Bielema said on Monday that he wants to narrow receiver targets for Allen down to six. However, due to the depth at receiver, Bielema and offensive coordinator Dan Enos are having trouble doing that. Keon Hatcher, the leading receiver from last season, is an obvious go, and with him Bielema mentioned Drew Morgan and Duwop Mitchell. At X, he listed Jared Cornelius, Cody Hollister, and Dominique Reed. He also wants Jojo Robinson and Luke Rossi to be involved. There are so many receivers to choose from that Bielema is considering redshirting Kendrick Edwards. As practice for UTEP proceeds, Bielema may be able to narrow down his wide receiver focus.

4. QB Brandon Allen has improved over the course of camp: Allen, including the rest of the Razorbacks offense, didn’t have a great first scrimmage. He completed 10 of 23 passes, had an interception, and missed several targets. During Saturday’s scrimmage, however, Allen went 17 of 22 for around 250 yards and four touchdowns. He also rushed for a fifth. He did have two interceptions, one on a bad screen pass that bounced off OL Dan Skipper and another on a bobbled reception. But overall, Allen showed offensive productivity. Most scores came from the red zone, an area where the first-team offense previously struggled, and Allen also scored on a two-minute drill.

5. Hunter Henry is primed to be a star of 2015: Named preseason first-team All-American by ESPN, Henry is arguably the best tight end in the country. While Bielema limited his play toward the end of camp, no doubt to preserve his health, all signs point to another great year for Henry. It will be interesting to see, though, how his role changes. Inconsistent play at receiver last year caused a heavy majority of the passing offense to fall on the shoulders of the tight ends. With a revamped receiving corps this year, receptions will be more evenly distributed.
