As an owner of all three, I value them as....
Edler is consistent, he puts up regular points on a powerhouse.
Shattenkirk is close behind, but still needs to prove he can break the fifty mark. I would bet on him though.
Carlson has tons of potential and ability, but has proven the least.
None of these guys are throw aways, but lots of great/bad trades are pulled based on potential and that is the diff. with Edler. He has proven himself.
If you put a gun to my head and said pick one. I take Edler.
