Jacksonville Jaguars mailbag

Got questions about the Jacksonville Jaguars? I’ll try to answer a representative selection of them every Saturday. Submit your questions via Twitter to @ESPNdirocco.

@ESPNdirocco: It's important for any running back, whether it's Adrian Peterson or Toby Gerhart. If there's no holes, it's hard for backs to get positive yardage. The Jaguars like to run the outside zone, and the interior of the offensive line plays a significant role in that. Fixing the center and right guard spots will be the key to the offense's success.

@ESPNdirocco: The hope is Allen Robinson be back on the practice field before the season opener. Even if he is, though, I wouldn't expect much out of him this season. Missing that much practice time at a position where rookies traditionally struggle may essentially make his first season a wash.

@ESPNdirocco: Outside of Blake Bortles, the player who has impressed me the most is defensive end Tyson Alualu, who has two sacks through the first two games. He had a great camp and is playing with a nasty attitude. The player who has been the most disappointing is center Mike Brewster, who has been given every chance to lock up the starting center spot but has struggled.

@ESPNdirocco: It's not about the number of victories. It's about showing progress. The Jaguars should be a better team this season, but a tough early schedule will make it hard for them to win significantly more games this season. I'm predicting them to win six games, but as long as there's visible progress, the season will be successful.

@ESPNdirocco: Both sides have had preliminary discussions and GM David Caldwell said he wants to keep Cecil Shorts around long term. As for whether the Jaguars let him walk, that depends on whether Shorts' asking price is unreasonable.

@ESPNdirocco: The defensive line has undergone a significant upgrade with the addition of Chris Clemons, Red Bryant and Ziggy Hood. That will be the most improved unit. As it was last year, the interior of the offensive line is the biggest weakness. It got an upgrade with Zane Beadles, but the center and right guard spots, as discussed above, are a huge issue.

@ESPNdirocco: No. That's not realistic until 2015.

@ESPNdirocco: I expect Allen Hurns to. Robinson won't contribute much this year and Ace Sanders is suspended for the first four games.

@ESPNdirocco: It depends on how this season plays out. The Jaguars don't seem to think Brewster is the answer, and Jacques McClendon doesn't seem to be a long-term option. Luke Bowanko, however, has a chance to win the job and they liked what they saw from him during the limited reps he's gotten. If they believe he's the long-term answer, then I don't see them making the position a high priority in free agency or the draft. There are several centers scheduled to become unrestricted free agents that fit the age profile the Jaguars would like (27 years old or younger). Stefen Wisniewski and Rodney Hudson top the list.
