Seventh in a series looking at lineup holes that are important even if they don't make headlines.
Everybody is talking about: Three defensive players who earned first-team All-Pac-10 honors need to be replaced: defensive tackle Brian Price, linebacker Reggie Carter and cornerback Alterraun Verner.
Bigger shoes than you think: The Bosworth brothers: defensive end Korey and weak side linebacker Kyle.
These two never became stars but they were multi-year starters who played hard and made plenty of plays for a good defense. Kyle ranked second on the Bruins in 2009 with 77 tackles, with 7.5 coming for a loss. Korey ranked sixth on the team with 58 tackles, 14 coming for a loss. He also broke up five passes.
Who is stepping in: There's not much experience at either position, and it's possible that incoming freshman will immediately enter the mix at both spots. At end, redshirt freshman Keenan Graham is atop the spring depth chart ahead of sophomore Iuta Tepa, who recorded a single tackle last year. There's also senior Reginald Stokes, who's seen plenty of action but is sitting out spring practices with a knee injury. His status for the fall is "undetermined." At linebacker, junior Sean Westgate will get first crack. He recorded 18 tackles last year. Behind him are true freshman Jared Koster, who grayshirted in 2009, and converted safety Glenn Love.
