Do we really need another 20 year old defenseman? As good as Jones might one day be, I'd look for a more established D who is already playing top pairing.
If I had to pick right now I'd say RNH is the odd man out, but the fact Hall/Drai are lighting the world on fire might have something to do with that.
To Edm: Hamonic and Nielson
To Nash: RNH
to NYI: Jones and Gaustad
