The third of a 10-part series that looks at where Pac-10 teams are strongest and weakest as they begin spring practices.
Strong: Defensive front seven
Why it's a strength: The Sun Devils take some significant hits on defense, losing seven starters, including five of their top six tacklers, but the young talent coming back is impressive, particularly up front. Start with the defensive line. Sure, end Dexter Davis is gone, but he's the only departure on the three-deep. And here's a guess that tackles Lawrence Guy, William Sutton and Corey Adams take a step forward in 2010. Linebackers Mike Nixon and Travis Goethel must be replaced, but rising star Vontaze Burfict returns inside and Gerald Munns, Brandon McGee and Shelly Lyons have experience. Count on this: The Sun Devils, owners of the conference's No. 1 rush defense in 2009, won't be easy to run against again next fall.
Why it's a weakness: It will not be a pattern of this feature to indict an entire side of the ball, but the Sun Devils have huge issues on offense for a third consecutive season. Last year, they ranked eighth in the Pac-10 in scoring and ninth in total offense. And only four starters are back this spring. Ouch. Skill positions? There's uncertainty at quarterback. The top two receivers are gone, as is starting tailback Dimitri Nance. The line? Three starters need to be replaced, including the unit's leader in 2009, tackle Shawn Lauvao. Answers may be found this spring. Steven Threet and Brock Osweiler will battle at quarterback, while Oregon transfer Aaron Pflugrad will immediately bolster the receiving corps. Injuries the past two seasons mean lots of returning guys on the line have experience. And there are plenty of choices at tailback. Still, there's a lot of uncertainty here.
