The seventh of a 10-part series that looks at where Pac-10 teams are strongest and weakest as they begin spring practices.
Why it's a strength: Junior free safety Rahim Moore led the nation with 10 interceptions last year and is a potential preseason All-American. So the Bruins should feel pretty good about that spot. Junior strong safety Tony Dye ranked fourth on the defense with 73 tackles, while his backup, junior Glenn Love, saw plenty of action and finished with 27 tackles. While life for the safeties might be a little bit more difficult without cornerback Alterraun Verner, the Bruins probably have the best returning crew at the position in the conference.
Weak: Defensive front seven
Why it's a weakness: The Bruins not only lost five starters from their front seven, they lost five quality starters, including stalwarts like defensive tackle Brian Price, linebacker Reggie Carter and the Bosworth brothers, end Korey and linebacker Kyle. What's more, the depth is questionable and/or inexperienced, particularly at defensive tackle. While any team would be glad to welcome back players like end Datone Jones or outside linebacker Akeem Ayers, the Bruins will be young up front and that typically is a reason to worry.
