Sunday afternoon, Houston heads to Jacksonville to take on an AFC South foe in the Jaguars. Houston is coming off of a bye while Jacksonville is fresh off a loss in Kansas City. With a 2-0 post bye record under Bill O’Brien, the stage is set for the Texans to keep rolling in the AFC South.

There are the keys to watch during Sunday’s game.

Blake Bortles Footwork

During his short tenure with the Jaguars, Blake Bortles has been a fairly exciting, albeit inconsistent, quarterback. Drawing comparisons to Ben Roethlisberger, Bortles is a gigantic human with a big arm and surprising scrambling ability. Unfortunately for Jaguars fans, he has often struggled to move the offense early in games, resulting too frequently in big deficits that are difficult to overcome. 2015 was the perfect example of this inconsistency as Bortles passed for 4,428 yards and 35 touchdowns for a Jaguars squad that still finished a measly 5-11. A good majority of these touchdowns came in garbage time as opposing defenses went into more of a prevent mode and allowed the Allens to run free.

So far, 2016 has been very similar as the Jaguars offense has failed to move the ball and put points on the board. Not all of these issues can be placed on Bortles’ shoulders as Chris Ivory has disappointed as a featured back, and Allen Robinson has dropped too many passes. However, Bortles still shares much of the blame with his 10 interceptions and only 14 touchdowns. The reason? The Jaguars quarterback has regressed as a pocket passer as his form has broken down.

Even NFL Media’s Chris Wesseling summed up Bortles’ struggles in an article about franchise question marks using a beautifully concise statement:

“Plagued by an awkward, hitch-filled throwing motion that would make even Tim Tebow blush, Bortles is a broken player as of the midpoint in his third NFL season…”

Wesseling’s analysis is spot on as this throwing motion causes Bortles to miss too many wide open receivers. His elongated delivery also gives edge rushers enough time to round the corner at notch sacks.

What does this mean for the Texans? Well, longer delivery times mean more opportunities for sack artists like Jadeveon Clowney and Whitney Mercilus. Plus, Jacksonville has issues protecting quarterbacks. This should be a long afternoon for young Bortles, at least until the fourth quarter.

Chris Ivory’s Rushing Struggles

This has been a weird season for Chris Ivory. Signed as a free agent, the former Saints and Jets running back missed the first two weeks of the season with injury before rushing for 12 total yards against the Ravens in his first game. Ivory has carried the ball 58 times for 236 yards and one touchdown, but almost half of those yards came in one game against the Chiefs. He looked near unstoppable against a solid Kansas City defense, rushing for 107 yards before the Jaguars were forced to throw the ball more. But that performance was an outlier. Ivory has been fairly terrible, failing to top 50 yards in any other games. Against Tennessee, he rushed four times for six total yards.

To be fair, Ivory has been sharing carries with T.J. Yeldon (70 carries for 253 yards), but he should be playing so much better. Ivory has shown some great talent in years past, but 2016 just hasn’t been the same. Will he keep rolling after a bigger game, or will Ivory go back to 20-30 rushing yards? Houston is ranked 28th against the run, so the opportunities will be there.

Beating the 5th-Ranked Pass Defense

Would you believe that the Jaguars have the fifth-best passing defense in the NFL? Surprising, right? Well, this ranking makes more sense when you consider that Prince Amukamara has been a solid free agent acquisition, and Jalen Ramsey has enjoyed a very good rookie season–minus his interactions with Steve Smith.

The Texans passing offense has struggled so far, and getting healthy against this Jaguars secondary may be a little tough. Beating Jacksonville’s defense will likely come down to Lamar Miller running against the 24th-ranked rush defense. Miller has been solid overall with his ability to gain tough yards on the ground or take screen passes for extra yards. If Miller breaks off some big runs, Jacksonville will have to bring extra defenders into the box, creating more favorable matchups for the passing offense.

Prediction: Texans Win

Obviously, AFC South matchups are more difficult to predict given the familiarity of the teams, but Houston should have the advantage on Sunday. Bill O’Brien has coached the Texans to major second-half improvements during his two years as head coach, holding an 11-4 post-bye record. Plus, the Jaguars offense simply can’t get out of its own way. Expect the front seven to create havoc and force multiple turnovers from Bortles.

Kickoff is Sunday at 1:00 p.m. ET.
