1. Washington (CB Sidney Jones Jr. S Budda Baker Jr. CB Kevin King Sr. S JoJo McIntosh So. CB Darren Gardenhire Jr.) - The Huskies are stacked in the secondary with three three-year starters who are all first-team All-Pac-12 talents with first round NFL Draft potential. This unit was very hard to pass against in 2015 and return all but one key player.
2. UCLA (S Randall Goforth Sr. S Jaleel Wadood Jr. CB Marcus Rios Sr. CB John Johnson Jr. S Adarius Pickett So. S Tahaan Goodman Sr.) - This unit is incredibly deep and experienced. Goforth, Wadood and Rios are all-conference players with countless starts and stats under their belts. The rest of the group has experience and raw talent that made them blue chip recruits.
3. USC (CB Adoree Jackson Jr. S John Plattenburg Jr. CB Leon McQuay Sr. CB Chris Hawkins Jr. CB Iman Marshall So. S Marvell Tell So.) - Adoree Jackson is the star of all stars, but don't sleep on the rest of this group. Plattenburg and McQuay are steady veterans and Marshall and Tell are absolutely stars in the making who might push the veterans out eventually.
4. Utah (S Marcus Williams Jr. CB Dominique Hatfield Sr. CB Reginald Porter Sr. S Justin Thomas Sr. S Jason Thompson Sr.) - Williams is the star here as the leader of a group which is quite adept at picking the ball off. Like the rest of the Utah defense, this unit it tough, physical and likes to make big plays.
5. Stanford (S Dallas Lloyd Sr. CB Quenton Meeks So. CB Alijah Holder Jr. CB Terrence Alexander Jr. CB Alameen Murphy Jr.) - The Cardinal are once again strong in the back of their defense. They don't have the stars other units above them have, but Lloyd, Holder and Alexander are strong veterans and Meeks is turning into a star.
6. Washington State (S Shalom Luani Sr. CB Marcellus Pippins Jr. CB Darrien Molton So. S Isaac Dotson Jr. CB Charleson White Jr.) - Oh have the Cougars made strides in their secondary. Former rugby star Luani is one of the best safeties in the conference and the group around him has really helped turn around the Cougar defense. Pippins is one of the most-underrated corners in the conference.
7. Colorado (CB Chidobe Awuzie Sr. S Tedric Thompson Sr. CB Ahkello Witherspoon Sr. S Afolabi Laguda Jr.) - Another unit which is making strides. Awuzie is an all-conference players and Thompson and Witherspoon bring the kind of talent and experience this Buff unit has lacked in recent seasons.
8. Cal (S Cameron Walker Sr. CB Darius Allensworth Jr. S Demariay Drew So. CB Antoine Albert Sr.) - We drop a little bit, but Walker, Allensworth and Drew have shown some promise, have talent and could turn this into a solid unit should they progress in 2016.
9. Arizona (S Tellas Jones Sr. CB DaVonte' Neal Sr. CB Jace Whittaker So. CB Jarvis McCall Jr.) - Not a bad unit that just lacks stars. Watch out for Neal to have a huge senior year though and for the rest of the starters to progress into stud players.
10. Arizona State (S Kareem Orr So. CB Chad Adams Jr. S James Johnson Jr. CB Armand Perry Jr.) - This group could very well climb the charts. Orr was an interception machine as a freshman and Adams and Perry are on the verge of becoming one of the better corner combos in the conference.
11. Oregon (S Tyree Robinson Jr. S Charles Nelson Jr. S Reggie Daniels Sr. CB Arrion Springs Jr.) - This unit is outrageously talented, but simply got shredded last season and won't have the pass rushing help it had in 2015. It would be a huge boost if they could get the speedy Nelson full-time.
12. Oregon State (CB Treston Decoud So. CB Kendall Hill Sr. S Gabe Ovgard So. S Devin Chappell Sr.) - This unit has a lot of potential and could leave Oregon State as one of the best in the conference, but they are coming off of a troublesome 2015 season.
