Neither UCLA quarterback Josh Rosen nor USC's Sam Darnold is officially eligible for the 2018 NFL Draft, but scouts from 20 teams have been credentialed for Saturday's Pac-12 showdown. That group includes the Bills, according to USC as reported by Rosen and Darnold might be the two best quarterback prospects in college football right now. The deadline for underclassmen to decide for the draft is Jan. 15. Darnold is a redshirt sophomore, Rosen is a junior.
