I think after the top twelve ( burrow, young, Tua, Thomas, Simmons, wirfs, jeudy, lamb, wills, epenesa, okudah and brown) there is precipitous drop off. If teams reach ala raiders>Ferrell last year or if a few of the QBs (love, Eason, Herbert) get pushed up then we have a shot at one of those guys.
As far as WR goes, I'm with the majority in that I'd rather wait, especially if it's between that and ruggs. I don't dislike him, and totally understand the intrigue with his speed, I just think you can find something similar at better value. If they're hellbent on wr at 15, I'd prefer Tee Higgins anyway. Doubt his timed speed is as fast but he seemed to have plenty enough speed to get behind defenses and averaged 20 ypc.
