Whether true or redshirt, these are the freshman in the Pac-12 who should have breakout seasons in 2016.
Arizona - Anthony Mariscal rFr. S - The Wildcats' best incoming recruits are on the offensive line where players have the toughest time making an impact as true freshmen, so I'm going with Mariscal. He is a little like a Scooby Wright at safety as a player who isn't a physical monster, but just seems to have a knack for making plays and big hits.He could help improve the back of Arizona's defense.
Arizona State - Zach Roberston rFr. G - A blue chip recruit in the class of 2015, Robertson redshirted last year and is ready for action in 2016. He is a massive force at 6'6 330 and his versatility to play guard or tackle could get him a starter job as a redshirt freshman.
Cal - Melquise Stovall Fr. WR - The former USC commit shined bright in spring practice after graduating early. He had seven receptions for 128 yards and two scores in Cal's spring scrimmage. Could be the star receiver in the making the Bears need after basically their entire receiver group left after 2015.
Colorado - Tim Lynott rFr. G - Lynott was one of the best recruits the Buffs have signed in recent history and has a great chance at becoming a starter in 2016. He has the potential to become one of the best linemen the Buffs have had in a long time.
Oregon - Dillon Mitchell Fr. WR - Mitchell is talented enough to get targets in the Pac-12's best receiver unit and he showed it in spring football. Mitchell had seven receptions for more than 100 yards and two scores in Oregon's spring scrimmage.
Oregon State - Christian Wallace Fr. CB - The gem of Oregon State's 2016 recruiting class could start at corner right away. He brings 6'3 205 size to the position and is as highly-regarded of a recruit as any player on the Beaver roster.
Stanford - Kaden Smith Fr. TE - Smith was arguably the nation's top tight end prospect in the Class of 2016 and he looks like he could be the next great Cardinal tight end. There is a lot of talent and experience at the position for the Cardinal, so it's doubtful he will set the world on fire as a true freshman, but with Austin Hooper gone early, I think he will have an impact right away.
UCLA - Migue Juarez Fr. LB - The Bruins are loaded at linebacker, but there is no way I see this guy who is listed at 6'2 230 coming out of high school not making an impact. He enrolled early to practice in spring and get his feet wet and could push veterans out of starting roles by the end of the season.
USC - Tyler Vaughns Fr. WR - The Trojans really need a playmaker to emerge next to JuJu Smith-Schuster and one of the nation's top recruits in the Class of 2016, Vaughns could be that player. He has great all-around skills and the size needed to step in right away.
Utah - Tyler Huntley Fr. QB - Huntley made the most of spring football and made himself a true player for the starting position come fall. Even if he can't beat out Troy Williams and Brandon Cox, there is still a chance you might see him play in 2016.
Washington - Sean McGrew Fr. RB - McGrew was arguably the West Coast's top running back recruit in 2016 and looks to be used as a versatile RB/WR for the Huskies right away. He is very small at 5'7 175, but lightning quick and could be the big play threat the Husky offense lacked last season.
Washington State - Jalen Thompson Fr. S - Thompson enrolled early and really impressed in spring practice. He has a chance to be the other safety starter across from Shalom Luani as a true freshman this fall.
