Here's a list of the Pac-10 players invited to the NFL combine, courtesy of The Sporting News.
First of all, it's incomplete. Underclassmen will be added later, such as USC receiver Damian Williams and UCLA DT Brian Price. And a number of seniors also will get invitations.
My immediate guess is that Washington linebacker Donald Butler and Oregon defensive end Will Tukuafu will end up receiving invitations, among others.
Arizona: DT Earl Mitchell, CB Devin Ross
Oregon State: QB Sean Canfield, OLB Keaton Kristick.
UCLA: OLB Kyle Bosworth, CB Alterraun Verner.
Washington: DE Daniel Te'o-Nesheim.
