As a general concept, no problem. If there was a Micah Parsons type LB then I would trade up for him. If there is a Revis type CB then no problem.
The issue is that there is not a Parsons type LB or Revis type DB in this draft.
It is debatable if Lloyd will be the best LB from this draft.
The position for Dax Hill is a question mark. His physical ability/size is similar to a CB but his college playing style sometimes resembled a LB. Sometimes that type of versatility is awesome (Micah Parsons) but more often it is jack of all trades, master of none.
Lloyd and Hill would be nice to have on the roster but relative to other options I'm skeptical.
Neither is on a tier above Zion or a couple of other OL options likely available at #24, IMO.
