Not sure about trading up, but definitely think trading back from 13 is the way to go.Its looking more and more to me like the best move is to trade down to the 19-23 range, pick up a 2nd Day (or TWO Day 3) pick, and Draft either BPA (Thielemann?) or Cooper, or Simpson.
This, or the trade UP, sacrificing future Capital for the TRUE impact player ( Love, Reese, Styles, Downs) just not feelin pickin at 13 right now, value wise.
