Re: OEL trade
OEL being bound to outproduce maybe both of your D makes me think you should try to acquire him.
I'm not too acquainted with what values 5-6th pick hold (I understand it's great value, so you could to bargain for a lesser return, that would be great for you) and obviously if you can mitigate your loss by trading one of your players it makes it for a good deal overall.
Looking at your forwards I would go with Carter or Sheary and probably keep both of your Ds.
