You can pick anyone and you get them in their prime for just the remainder of this season. I feel like Boselli is the obvious answer. Although, imagine having Big John Henderson in the middle of that D-Line to start getting some more pressure up the middle.
I ran into him in Ft Lauderdale spring break two years ago. Thanked him for the sacksonville years and told him we would love to see him back in a jags jersey. 48 hours later he signed with the ravens.
