College Football Nation: Aaron Zagory
Posted by ESPN.com's Ted Miller
Every Pac-10 team will be young somewhere... so what are the green units?
Arizona -- OT: Both starting tackles are gone, including potential NFL first-round pick Eben Britton. The four tackles on this spring two-deep roster have combined for only five starts, all by right tackle Adam Grant.
Arizona State -- QB: Combined starts of the five candidates to replace Rudy Carpenter at quarterback? Zero.
California -- TE: When Cameron Morrah, the Bears second-leading receiver in 2008, unexpectedly bolted a year early for the NFL draft, he left behind four combined receptions for backups Tad Smith, Anthony Miller and touted redshirt freshman Spencer Ladner.
Oregon -- DT: Both starting defensive tackles are gone and this unofficial depth chart shows 14 combine tackles for seven potential replacements.
Oregon State -- DE: Sackmasters Victor Butler and Slade Norris and their 41.5 combined sacks over the past two seasons are gone. Sophomore Kevin Frahm and senior Ben Terry, who split two sacks between themselves in 2008, are in.
Stanford -- K: Kicker Aaron Zagory is gone and either Travis Golia or David Green will take over, though neither has kicked a college field goal.
UCLA -- P: After four years of huge boots, punter Aaron Perez is gone. Redshirt freshmen Jeff Locke and Danny Rees will compete to replace him.
USC -- LB: All three starting linebackers, including All-Americans and future first-round draft choices Rey Maualuga and Brian Cushing, are gone. Chris Galippo, Malcolm Smith and Michael Morgan aren't exactly chopped liver, though.
Washington -- K-P: The Huskies need to replace both specialists with players who have no college experience.
Washington State -- TE: Devin Frischknecht and Ben Woodard, the top two guys on the 2008 depth chart, are gone and the expected replacement, JC transfer Peter Tuitupou, unexpectedly opted to go on a two-year church mission.
