Keeper Question

I'm keeping Kuechly, Watt, and Harrison Smith. Need a fourth keeper. Tackles 2pts and assists are 1pt.
FF 4 pts, FR 3 pts, sacks 3 pts and INTs are 4pts. I can trade for Laurinaitis 8th rd pk, Tyvon Branch 10th rd pk, Antrel Rolle 10th rd pk, Mark Barron 10th rd pk or Tulloch 10th rd pk. Who would you try to get? I have Brad Jones who I could keep and not give up a pick but I have some extra picks and rather go with one of the other players mentioned.

I actually think Jones is likely going to be a solid LB2 this season. If you don't choose him, I'd go James L.
