QB Josh Rosen UCLA - Rosen completely lived up to the huge hype he had coming into the season. He threw for more than 3,000 yards and 20 touchdowns and rarely looked like a freshman, let alone a true one.
RB Myles Gaskin Washington - More than 1,100 yards and 10 touchdowns, Gaskin wasn't just one of the conference's best freshman running backs, he was one of the conference's best backs regardless of class.
RB Ronald Jones USC - Jones ran for almost 900 yards and scored seven touchdowns and it still seemed like he only scratched the surface of what he can do. Jones is a star in the making.
WR Britain Covey Utah - The true freshman who wasn't a big recruit led Utah in receiving with more than 40 receptions, 500 yards and four touchdowns.
WR Chico McClatcher Washington - McClatcher actually made a huge impact on reverses and fly sweeps as he took three for touchdowns and also caught one.
TE Dalton Schultz Stanford - Schultz is listed as a sophomore by Stanford, but he redshirted in 2014. He had more than 100 yards receiving and a touchdown.
OL Kaleb McGary Washington - The redshirt freshman emerged as a great run blocker for the Huskies.
OL Trey Adams Washington - The true freshman showed huge potential as he eventually became Washington's starter at left tackle.
OL Layth Friekh Arizona - Friekh struggled at times, but started in a very tough position as a freshman.
OL John Lisella Colorado - Another player thrown into a tough spot who made the most of it as a freshman starter.
OL Chuma Edoga USC - USC inserted the elite recruited at times because he was too good to keep off the field.
DL Greg Gaines Washington - The redshirt came in for the very good Elijah Qualls when he was injured and the Husky front didn't miss a beat.
DL Hercules Mata'afa Washington State - Part of a Cougar front that was quietly among the best in the conference, he made a lot of plays in the backfield.
DL Solomon Thomas Stanford - The redshirt stepped up and played huge as part of a depleted and injured Stanford front.
DL Noah Jefferson USC - The most-exciting young player on USC's defensive line.
LB Cameron Smith USC - The only choice for Pac-12 Defensive Freshman of the Year. A future All-American and likely Pac-12 Defensive Player of the Year.
LB Rick Gamboa Colorado - Helped pick up where Addison Gillam left off and was a tackling machine.
LB Jonathan Willis Oregon State - The best young player on the Oregon State defense.
DB Kareem Orr Arizona State - Led the Pac-12 in interceptions with five even while missing time to injury.
DB Iman Marshall USC - An elite recruit who lived up to his billing and flashed star potential.
DB Quenton Meeks Stanford - Made some huge interceptions for Stanford.
DB Gabe Ovgard Oregon State - One of the young players Gary Andersen hopes to build around.
K - NA
P - Alex Kinney Colorado - The leading freshman in punt average.
