Here are some Pac-12 players who have a chance to emerge as big-time contributors in 2016:
Trey Griffey, WR, Arizona: Cayleb Jones, Johnny Jackson, and David Richards are all gone from Arizona's receiving corps, so this may be the year for Griffey -- son of the newly minted MLB Hall of Famer -- to emerge as a big-time contributor. At 6-foot-3, Griffey is one of the only Wildcat receivers featuring plus size, and he has already delivered some electric production in the past.
N'Keal Harry, WR, Arizona State: Some recruiting services tabbed Harry as the nation's No. 1 receiver prospect in this past year's class. The Sun Devils will be counting on him to contribute immediately a year after losing Devin Lucien and D.J. Foster.
Melquise Stovall, WR, California: It can be argued that Stovall already broke out as an early enrollee during the Golden Bears' spring game, when he torched the defense with an onslaught of catch-and-run production. Pac-12 defense should find the 5-foot-9 Stovall particularly slippery this year.
Demetris Robertson, WR, California: The Bears will feature two true super freshmen at receiver. Stovall is one; Robertson is the other. New quarterback Davis Webb, a fifth-year graduate transfer, should have fun throwing to these two explosive youngsters.
Josh Tupou, DL, Colorado: The Buffs already know that Tupou is good; he started all of their games in 2013 and 2014. But the big lineman was suspended last year, and that hurt the defense. Now, Tupou returns with the opportunity to play alongside Jordan Carrell, so we may see Colorado take significant strides up front.
Seth Collins, WR, Oregon State: Last year's starting quarterback almost transferred away from Corvallis, but Collins is officially back in a Beaver uniform. He's now at a different position, though. Will the athleticism that generated some thrilling (albeit dangerous) midair flips last season create effectiveness on the perimeter?
Soso Jamabo, RB, UCLA: The Bruins must replace Paul Perkins, one of the top backs in school history. Jamabo seems to be a prime candidate for that role. At 6-foot-2, he's a tall back, and also one that comes with plenty of hype: Jamabo was one of the top backs in the nation back during his recruiting cycle.
Sunia Tauteoli, LB, Utah: The former Utah State commit will turn 24 before he plays his first game in a Utes uniform, but he's expected to be a key figure in their effort to replace all of their starting linebackers from a year ago.
James Williams, RB, Washington State: The Cougars, so often incorrectly stereotyped into the "they don't run" category that's associated with Air Raid offenses, actually have a plethora of backfield talent. The newest addition to the group is Williams, whose talent may earn him the opportunity for some big runs in 2016.
Porter Gustin, LB, USC: The Trojans need to bring heat off the edge while maintaining discipline against speedy Pac-12 backs in the flats, and Gustin -- once a touted recruit -- is the man for that job. He may well be lined up for a big season.
Trenton Irwin, WR, Stanford: The Cardinal have graduated top wide receiver Devon Cajuste, so there's an opening in that corps, and Irwin is the player grabbing the opportunity by the horns. He may be Stanford's best route runner, and on an offense loaded with skill-position weapons, there will be plenty of chances for productivity.
Canton Kaumatule, DL, Oregon: The Ducks must replace a boatload of talent up front, and Kaumatule has always been tabbed as a promising prospect because of his size. At 6-foot-7 and 295 pounds, now is the time for him to shine.
