Here's a look back at the four classes Chip Kelly signed as head coach and the first two classes Mark Helfrich has signed. (We'll update Helfrich's final rankings -- including the surprise signing of Mattrell McGraw -- after the Ducks officially announce their class later today.) For consistency's sake, we use Rivals as the source of data.
