I'll take :

Caleb Williams
Marvin Harrison Jr
Quinyon Mitchell
Laiatu Latu

If we're limited to guys who we will be able to draft at 19 - hopefully:

Latu
Newton or Murphy
Payton Wilson
Ladd McConkey

If we're going one guy who is projected to be there when we pick:

19 - ED: Latu
52 - WR: Pearsall/Corley/R. Wilson
83 - OL: Beebe/Puni/Paul
99 - DL: Hall/Wingo/Sweat (if he promises to sit down with AD once a week and have a long talks about what it takes to be great)
