Ranking the 2015 Pac-12 receiver units: Oregon has best receivers in Pac-12

1. Oregon - WR Byron Marshall (Sr.) WR Darren Carrington (So.) WR Devon Allen (So.) WR Bralon Addison (Jr.) WR Dwayne Stanford (Jr.) TE Evan Baylis (Jr.)

The Ducks quickly went from having a question mark at WR/TE to having the deepest and most talented unit in the conference. Marshall exploded in 2014 after two good years at running back and will be the leader flanked by an endless pool of young receivers who had excellent years in 2014. The X factor here is Addison, who was a developing star before missing 2014 with an injury. This unit could be very scary if he comes back at full speed.

2. Cal - WR Kenny Lawler (Jr.) TE Stephen Anderson (Sr.) WR Bryce Treggs (Sr.) WR Trevor Davis (Sr.) WR Darius Powe (Sr.) WR Maurice Harris (Sr.)

Jared Goff has a wealth of talented and proven receivers to throw to even with Chris Harper gone to the NFL. Lawler is a huge receiver with good speed, Anderson is the conference's best pass-catching tight end, Treggs is a great, smaller receiver and the rest are nice depth players.

3. Arizona - WR Cayleb Jones (Jr.) WR Samajie Grant (Jr.) WR Trey Griffey (Jr.) Nate Phillips (Jr.) WR DaVonté Neal (Jr.) WR David Richards (Sr.)

This younger group is starting to really come into its own led by first-team All-Pac-12 level Jones, who is the conference's second-leading returning receiver. Grant is a budding star and Griffey, Phillips and Neal are as nice of a depth trio at receiver as you can find in the conference outside of Oregon.

4. Washington State - WR River Cracraft (Jr.) WR Dom Williams (Sr.) WR Gabe Marks (Jr.) WR Robert Lewis (So.) WR Tyler Baker (Sr.)

The Cougars have another deep group of good receivers even with Vince Mayle gone. Cracraft will become the Cougars' main go-to guy now with Williams as an excellent second-option. The key here is Marks, who was an All-Pac-12 guy before redshirting strangely in 2014.

5. UCLA - WR Jordan Payton (Sr.) WR Eldridge Massington (So.) WR Thomas Duarte (Jr.) WR Devin Fuller (Sr.) WR Mossi Johnson (So.) WR Kenneth Walker III (Jr.)

This long frustrating unit started to break through in 2014, led by a big year by Payton who is now one of the best receivers in the conference. The big thing with the Bruins is the continued development of the receivers around Payton.

6. Oregon State - WR Victor Bolden (Jr.) WR Jordan Villamin (So.) WR Richard Mullaney (Sr.) WR Hunter Jarmon (So.) TE Caleb Smith (Sr.)

Bolden and Villamin are budding stars with opposite games - Bolden is tiny while Villamin is bigger than a lot of tight ends. They will get a huge boost if Mullaney can come back healthy and reach his 2013 level.

7. Stanford - WR Devon Cajuste (Sr.) TE Austin Hooper (Jr.) WR Michael Rector (Sr.) TE Greg Taboada (Jr.) WR Francis Owusu (Jr.)

Stanford's never known for great receivers, but Cajuste and Rector are nice possessions receivers and Hooper should turn into the conference's best tight end in 2015.

8. Arizona State - WR D.J. Foster (Sr.) WR Cameron Smith (Jr.) WR Gary Chambers (Sr.) TE Kody Kohl (Jr.) WR Ellis Jefferson (So.) WR Frederick Gammage (Jr.)

Moving one of the conference's best running backs, Foster, to receiver gives this unit a huge boost after the loss of Jaelen Strong.

9. USC - WR Juju Smith (So.) WR Darreus Rogers (Jr.) CB Adoree Jackson (So.) WR Steven Mitchell (So.)

Smith is the next star receiver at USC, but the rest of this unit is shockingly thin. Jackson will help out a lot here though.

10. Colorado - WR Nelson Spruce (Sr.) WR Shay Fields (So.) WR Bryce Bobo (So.) TE Sean Irwin (Jr.)

This is pretty much all about Spruce, the Pac-12's best receiver.

11. Washington - WR Jaydon Mickens (Sr.) TE Joshua Perkins (Sr.) WR Dante Pettis (Jr.) TE Darrell Daniels (Jr.)

The Huskies took a major blow losing speedster John Ross for the season but do have a very good option in Mickens and one of the conference's best pass-catching tight ends in Perkins, coming back.

12. Utah - WR Kenneth Scott (Sr.) WR Tim Patrick (Sr.) WR Delshawn McClellon (Jr.) TE Siale Fakailoatonga (Jr.)

There isn't a ton of experience, depth or talent here after the loss of Dres Anderson, Kaelin Clay and Westlee Tonga.
