My first thought is that I wish I had your problems...
If I absolutely *had* to choose one to drop, I'd say Barron, only because Ogletree might be back this season and take his LB spot back. Barron's extra value is DB categorization, but playing LB.
I think Barron is #1 on the list, but he has a good point. Is there now way to get another guy if Ogletree comes back? because Barron is a full on elite safety right now.
