Spring practices end the retrospective glances at the last season and begin the forward-looking process of the next fall. Departed players need to be replaced and returning starters need to get better and youngsters need to step up.

While some teams have more issues than others, every team has specific issues that will be front and center. So we begin a look at the main questions each Pac-12 team will address this spring.

Continuing our reliance on the Roman alphabet, Arizona State is up next.

1. How do you even begin to replace Jaelen Strong? Strong hauled in 82 passes for 1,165 yards and 10 touchdowns -- including one amazing Hail Mary that brought us “Berco-ing.” If you haven’t thanked him yet for that alone, you should. Head coach Todd Graham has said do-everything back D.J. Foster would move to wide out, despite rushing for 1,081 yards last year. Look for a dusting of him in the run game -- a la speed sweeps, fly motion etc. -- but given the depth at running back, the move makes sense. Especially since Foster already has 163 catches for 1,874 yards and 11 touchdowns for his career. Nice luxury to have your 1K rusher become your go-to wide receiver.

2. How much will special teams be a factor? A lot. Count on it. Graham made special teams a point of emphasis in 2014 after a fairly abysmal 2013. The Sun Devils are in good shape with kicker Zane Gonzalez, but they’ll work with Matt Haack to become more consistent. The return game will be a priority, with Dechavon Hayes making the jump off of the scout team. The coaching staff loves his speed and he’ll likely be penciled in as the punt returner. Look for Kalen Ballage, who had a fantastic return day against Duke in the Sun Bowl, to stay with kickoff return duties.

3. Tackle talk? Perhaps more important than replacing Strong will be protecting presumed starting quarterback Mike Bercovici on the corners. With both offensive tackles -- Jamil Douglas and Tyler Sulka -- departing, the Sun Devils will look first to Evan Goodman at left tackle and Billy McGehee at right tackle. There’s some depth here, which helps. Freshman Quinn Bailey could get a look, and guard Christian Westerman could move outside, opening up Stephon McCray as an option inside.
