Points only keeper - looking for a dman to give me decent point total for the rest of this season, who won\'t be protected.

I don\'t have room to protect Carle, but a guy wants him and is willing to give me a vet D (Blake or Aucoin) plus a draft pick.

Which of these 3 will produce the most the rest of the way?
Aucoin
Blake
Carle

I like Carle long term but since i\'d lose him for nothing, looking to move up and push for the $ and get a better draft pick.
