Detellier On Draft/Saints

Lets say there is not a player at 10 the saints want and no other team is willing to trade up, would it make sense to take the highest rated player like Djack and then attempt to trade him with a team behind the saints?

Is having the player a team wanted more leverage than the 10th pick? My thinking is that the team may have originally thought Djack would fall to them and if the saints dangle him in front of their face they would be very tempted.
