Next up in our NFL Preview, the top 5 questions for the AFC South. Check out the previews for the AFC East and the NFC East.

#5 – Will DeMarco Murray make a significant impact to Tennessee’s offense?

The 2014 rushing leader definitely struggled in Philadelphia’s offense last season. While there are reports of Murray impressing in camp, it also seems likely that rookie Derrick Henry will have plenty of touches as Tennessee continues to build the offense.

It’s unclear just how good Murray can be and if he’ll regain his 2014 form, but he should be able to help make the running game a weapon that can take some pressure off of Marcus Mariota.

#4 – Will everything come together for Jacksonville?

The Jaguars are projected to do very well in 2015. The offense seems loaded with Blake Bortles, T.J. Yeldon, Chris Ivory, Allen Robinson, Allen Hurns, and Julius Thomas. The defense has many young players and also seems complete and ready to take the next step towards the playoffs.

The difficult hurdle that all young teams have to overcome is whether or not talent and opportunity meet success. All signs point to Jacksonville having a great chance to win the AFC South and make the playoffs, but it will likely come down to whether or not the young defense can take a big step forward and also if Blake Bortles can continue his success.

#3 – Can Marcus Mariota avoid a sophomore slump?

In his first season, Marcus Mariota met most expectations and gave fans a reason to believe that their beloved Titans can compete in the AFC South.

While he missed a few games last season, Mariota showed he can be effective in the passing game and also be a threat to run when needed. Avoiding a sophomore slump will be the big challenge in 2016, but with tight end Delanie Walker and wide receiver Dorial Green-Beckham to pass to and an emerging ground attack, the odds are better than not that Mariota will have another good season this year.

#2 – Will Brock Osweiler be a legitimate starting quarterback?

Osweiler filled in nicely last season for Peyton Manning as posted a 5-2 record and threw 10 touchdowns to 6 interceptions. The question now becomes, how well will he play for an entire season as a starter?

He will have a good team around him with receiver DeAndre Hopkins, running back Lamar Miller and of course, J.J. Watt leading the defense. If Osweiler can play well for the whole season, the Texans will also be heavily competing for the AFC South title.

#1 – Will the Colts be able to protect Andrew Luck?

Last season, Andrew Luck took a beating. The Colts addressed the offensive line problem by drafting the best center in the draft, Ryan Kelly, which should strengthen a very important piece on the line.

Anthony Castonzo is the anchor at left tackle and third-year veteran Jack Mewhort seems to be settled in at left guard. With Kelly at center, the only positions in question are right guard and right tackle.

The Colts also drafted tackle Le’Raven Clark in the third round and guard Joe Haeg in the fifth.

Le’Raven Clark and Joe Reitz seem to be battling it out for the right tackle position and incumbent left guard Hugh Thornton will likely beat out Haeg for the starting job, but it appears the offensive line may finally be a strength for the Colts in 2016.

If Luck is upright and Frank Gore can cheat Father Time one more season, the Colts’ offense should be back to where it was in 2014, if not better.
