azcentral sports’ Jeff Metcalfe covered Arizona State’s spring football practices.

What are some areas of concern? Here are five things to examine.

This is Part 2 of a series. Scroll to the bottom for the full schedule.

The back end

Nothing would be more rewarding and significant than for the personnel and coaching resources being invested in the secondary to pay off with:

  • A position group that tackles better.
  • Comes up with more takeaways.
  • Is not last nationally in passing yards allowed.

With seven new defensive backs on board for fall camp, there is hope but also plenty of unknowns.

Linebacker depth 

Is there enough depth to absorb injuries particularly at linebacker, where only DJ Calhoun started every game last season?

That remains an uncertainty even after extensive development work in the spring with Malik Lawal, Khaylan Thomas and Deion Guignard.

Incoming LB Kyle Soelle may need to break through for competition and injury protection.

QB rebound

Quarterback was such a snakebit position in 2016 that Dillon Sterling-Cole was forced to give up his redshirt year, the Sparky formation was used all over the field and walk-on wide receiver Jack Smith took some snaps at his high school position.

With the addition of transfer Blake Barnett, QB is more stable and competitive.

Now it’s a question of productivity no matter who wins the starting job.

O-line continuity

ASU signed some promising offensive linemen under former O-line coach Chris Thomsen, now at TCU.

Those players are under the development of Rob Sale for now and the near future since only two in the post-spring depth chart are seniors.

To take advantage of skill players, particularly at running back, the O-line must stay healthy to gain cohesiveness and perform better (ASU was No. 112 in rush offense and No. 123 in sacks allowed in 2016).  

New specialists

ASU has done a fine job lining up replacements for Groza Award-winning kicker Zane Gonzalez and punter Matt Haack.

But Brandon Ruiz, for all his high-school credentials, is a freshman facing much greater pressure while Michael Sleep-Dalton hasn’t punted in a game since 2015.

If they come close to their potential, special teams will remain a plus at least from the kicking standpoint for years to come.
