California is looking for a new defensive coordinator. Bob Gregory, who's been at Cal since coach Jeff Tedford was hired in 2002, is leaving to become a defensive assistant at Boise State, where he coached before landing in Berkeley. "I appreciate Bob's dedication and loyalty to the Cal football program over the last eight seasons," Tedford said in a statement. "This was coach Gregory's decision all the way to make what he feels is the best move for his family. I admire Bob both as a professional and a friend, and respect his value of family. I support his decision to do what's best for his family and wish them all the best as they move forward." Despite welcoming back eight starters from a strong 2008 defense, Cal ranked seventh in the Pac-10 in scoring (25.5 ppg) and total defense (379 yards per game). Tedford has said this offseason the Bears will look at adopting more aggressive defensive schemes. It's not clear what role Gregory will play at Boise State. The Broncos recently lost their defensive coordinator, Justin Wilcox, to Tennessee, but Pete Kwiatkowski was promoted from defensive line coach to coordinator. Gregory's specialty in the past has been the secondary, but Marcel Yates is the Broncos secondary coach.
