Vernon Adams Sr. QB - Oregon from Eastern Washington
Adams at worst will be a major competitor to win the starting job that loses out to Jeff Lockie and becomes an excellent backup option. At best, the FCS star who torched Oregon State and Washington at Eastern Washington will make the transition out of the Marcus Mariota era much easier than it seemed it would be before he decided to transfer.
Matt Hegarty Sr. C - Oregon from Notre Dame
Hegarty might be an even bigger score for the Ducks than Adams as a graduate transfer. A starter at Notre Dame, Hegarty will likely replace Hroniss Grasu. While he won't be able to fill Grasu's All-American shoes, he will probably do a better job than one of the younger linemen who were expected to before his transfer.
Brennan Scarlett Sr. DE - Stanford from Cal
This one stings for the Bears, as Scarlett would have been one of the better players on Cal's defense, but he is now an instant-impact grad transfer for the Cardinal. He could start right away on a Stanford defensive line that lost every starter from 2014 if he can finally get consistently healthy.
Freddie Tagaloa Jr. T - Arizona from Cal
The massive (6'8 316) Tagaloa started a handful of games at Cal early in his career and could easily slide in for the departed Fabbians Ebbele or Mickey Baucus at tackle for the Wildcats.
Ahmad Christian Sr. CB - Utah from South Carolina
Christian heads to Utah from SEC country where he was a contributor for the Gamecocks. He has a chance to be a starter in a Utah secondary that was gutted by graduation after 2014.
Kylie Fitts Jr. DE - Utah from UCLA
Fitts left a crowded UCLA defensive line for the greener and more open pastures of Salt Lake City. He has impressed thus far and could start opposite Hunter Dimick and become part of a really good defensive line.
James Looney So. DT - Cal from Wake Forest
Looney was going to become a starter if he stayed at Wake Forest, but headed out west where there is a ton of opportunity on a cluttered Cal defensive line. He has a chance to start at Cal or at least get significant time.
Devin Lucien Sr. WR - Arizona State from UCLA
Lucien was a solid fifth or sixth option for Brett Hundley the past few years and now heads to Arizona State as a grad transfer to play in a receiver group that is less crowded with experience and talent. I think he will be an excellent third or fourth option for Mike Bercovici.
These transfers are coming to the Pac-12, but are not expected to have much of an impact in 2015.
Jaleel Awini Jr. LB Colorado from Air Force
David Catalano Sr. G Arizona from San Jose State

Ty Griffin So. QB - Oregon from Georgia Tech
Jarek Hilgers So. S - Arizona from Arizona State
