I have these D in a 12 team Dynasty League:

Edler
OEL
Fowler
Adam Larsson
Spurgeon
Dougie Hamilton

I think I have one of the strongest set of D, but I usually only try to carry 5 at the most. I also am kinda weak up front, so who should I try to move?

I was thinking either Fowler or OEL, because I think I could get the most for them. But who would carry the bigger value? And also, which of the 2 are expected to develop into a more offensive D?
