The Pac-12 saw 13 players declare for the 2017 NFL draft, which is down from 15 last year, 16 in the 2015 draft and 25 in 2014.
Here is a look at who is leaving and how each school will replace those players:
Cal
WR Chad Hansen: Hansen finished the season with 92 catches for 1,249 yards, but at this time last year he was a relative unknown and the Bears had to replace their top six pass-catchers from 2015. This offseason is different because it’s clear there are two potential stars in rising sophomores Demetris Robertson (50 catches, 767 yards) and Melquise Stovall (42 catches, 415 yards).
Stanford
RB Christian McCaffrey: Stanford got a glimpse at its future in the Hyundai Sun Bowl, when sophomore Bryce Love was the feature back following McCaffrey’s decision not to play. The results were encouraging: Love ran for 115 yards to finish the season with 779 yards on 112 attempts (7.0 yards per carry).
DE Solomon Thomas: Thomas was clearly the best player on the field in the Cardinal’s victory against North Carolina, and his departure might actually be a tougher void to fill than that of his more heralded teammate. There isn’t a player on the roster who can replicate what Thomas did (there’s a reason he turned pro, after all), but Harrison Phillips instantly becomes the team’s most important defensive lineman and, like Thomas, can play on the interior and at end.
UCLA
DL Eddie Vanderdoes: There were stretches during the season in which Vanderdoes was one of the more dominant defensive linemen in the conference, but he didn’t seem to be quite as effective late in the year. Look for Boss Tagaloa, who was in the rotation as a true freshman, to quickly develop into one of the best interior defensive linemen in the conference.
USC
CB Adoree' Jackson: Jackson’s impact won’t be matched by anyone, but Jack Jones comes in a similar mold. He figures to have a good chance at starting opposite Iman Marshall and, like Jackson, could turn into the team’s primary punt returner.
OG Damien Mama: Mama’s departure was the most surprising of USC’s three early entrants and his absence won’t be hard to account for. At this point, the most straightforward succession plan would simply be to have Toa Lobendahn, who was lost for the season due to injury in Week 1, to plug in at left guard. Lobendahn was the center to open 2016, but Nico Falah played well after replacing him. It would make sense for Falah to remain at center and have Lobendahn take Mama’s spot, where he has already made eight career starts. The other option would be to have Chris Brown, who started in front of Mama against Alabama, back in that spot, but he is expected to move to tackle.
WR JuJu Smith-Schuster: Even before his 13-catch, 164-yard, three-touchdown Rose Bowl, Deontay Burnett was well on his way toward establishing himself as the heir apparent to Smith-Schuster as USC’s No. 1 receiver, but his memorable performance ensured he won’t sneak up on anyone next season. Tyler Vaughns, Michael Pittman and Trevon Sidney are three other names to keep an eye on.
Utah
LT Garett Bolles: In just one season in Salt Lake City, Bolles turned into a big-time NFL prospect. Jackson Barton will be the favorite to replace him. Barton was the primary backup for both Bolles and right tackle Sam Tevi, and at 6-foot-7 and 310 pounds has the frame to turn into an NFL prospect himself.
S Marcus Williams: When Williams was sidelined due to injury, Jordan Fogal, a former walk-on, was his replacement. In his first career start, against UCLA, Fogal had five tackles and two interceptions.
Washington
WR John Ross: Ross and Dante Pettis formed one of the best receiver tandems in the country this season, and the Huskies still figure to be in good shape with Chico McClatcher alongside Pettis in 2017. As a sophomore, McClatcher caught 31 passes for 574 yards and five touchdowns.
S Budda Baker: As the season went along, Taylor Rapp became a more important part of the Huskies defense and with Baker’s departure for NFL, Rapp has a good chance at becoming the face of the secondary playing alongside fellow safety Jojo McIntosh.
CB Sidney Jones: The Huskies will also need to replace their other starting cornerback, Kevin King, which will free up opportunities for players such as Jordan Miller, Austin Joyner and Byron Murphy.
DT Elijah Qualls: Qualls was ready to make the jump, but a lot of people thought Vita Vea -- all 6-foot-4, 346 pounds of him -- was too. Vea was a second-team All-Pac-12 selection despite starting just three games during the regular season and has a chance to develop into a first-round pick.
