The Arkansas Razorbacks open up the 2015 season against the UTEP Miners tomorrow with the entire country picking the Hogs to roll. In fact, the only question for all the gamblers out there is whether or not the Razorbacks will cover the 33 point spread.

Even with the odds solidly in their favor, the Razorbacks have several questions annoyingly hovering above their heads going into the game Saturday. Fans are excited to get their first look at some players, and to see how the team has developed under the tutelage of Coach Bret Bielema.

Here are the 5 biggest questions for the Razorbacks heading into their first game.

5. Defensive Depth

The Arkansas Razorbacks defense really turned up the heat last year down the stretch, with shutouts of LSU, Ole Miss, and a beat down of Texas in the Texas Bowl. However, the Hogs lost Darius Philon, Martrell Spaight, and Trey Flowers, who all ended up in the NFL and were 3 of the 4 leading tacklers for the team last season. The Razorbacks also lost cornerback Tevin Mitchell, linebacker Braylon Mitchell, and defensive back Alan Turner. The Hogs have to replace a lot of tacklers and playmakers, and are very young in the secondary.

The defensive line has been the star of the defense in the preseason for the Hogs. The depth on the line is strong, especially on the interior with Bijohn Jackson, Taiwan Johnson, Hjalte Froholdt, and Demarcus Hodge. Lining up at the end position, the Hogs are strong with JaMichael Winston, Deatrich Wise, and Tevin Beanum.

The questions start to pop up when you get to the linebackers. Obviously, team captain Brooks Ellis is poised to have an All-SEC caliber year now that he’s replaced Spaight in the Weakside Linebacker position. (Spaight led the SEC in tackles last year.) Backing up Ellis is his former high school teammate and true freshman Dre Greenlaw. The Fayetteville native has impressed coaches in the offseason. It is always surprising to see a true freshman play in the SEC in a non-skill position. Time will tell if Greenlaw will be able to make it through the grind of the season.

The secondary for the Razorbacks will have a lot of new players for the Hogs as well. The Razorbacks will welcome back senior Strong Safety Rohan Gaines. Also returning is junior cornerback DJ Dean who started 6 games last year for the Hogs, and Jared Collins, who started 12 games last season. Pine Bluff Dollarway’s Josh Liddell saw limited playing time last year, and has earned a starting role in the secondary. Redshirt Freshman Santos Ramirez has made some big plays in practice this offseason, and is expected to see some playing time in the safety position.

The Razorbacks have to replace 2 linebackers, 2 corners, and 2 defensive lineman. The starters are game tested for the most part, but their backups have seen little to no action in the SEC. The Razorbacks are still building the depth chart that was decimated after coaching changes and transfers.
